              alternans down to one-millionth of a volt. T-wave
              alternans is an alternating pattern in the ECG  
              which has been associated with sudden death and 
              with life threatening heart rhythm disturbances.

                               PROSPECTUS SUMMARY
 
  The following summary is qualified in its entirety by reference to the more
detailed information and the Company's financial statements and related notes
thereto included elsewhere in this Prospectus. Investors should carefully
consider the information set forth under the heading "Risk Factors". Except as
otherwise noted herein, all information contained in this Prospectus (i) gives
effect to a 1-for-2 reverse split of the Common Stock to be effective prior to
the closing of this Offering, (ii) reflects the conversion of all outstanding
shares of the Company's Series A and B Convertible Preferred Stock (the
"Preferred Stock") into an aggregate of 4,455,708 shares of Common Stock, and
(iii) assumes no exercise of the Underwriters' over-allotment option.
 
                                  THE COMPANY
 
  Cambridge Heart, Inc. ("Cambridge Heart" or the "Company") is engaged in the
research, development and commercialization of products for the non-invasive
diagnosis of cardiac disease. Using innovative technologies, including
proprietary disposable electrodes, the Company is addressing such key problems
in cardiac diagnosis as (i) the identification of those at risk of sudden
cardiac death, accounting for of approximately 50% of all deaths due to heart
attack, (ii) the early detection of coronary artery disease and (iii) the
prompt and accurate diagnosis of heart attack.
 
  With the emergence of new preventive therapies for sudden cardiac death
(implantable defibrillators and radio frequency ablation), the Company believes
that the accurate diagnosis of patients needing these therapies has become
increasingly important. Existing non-invasive diagnostic tests generally either
identify only a small subset of patients who are at risk of sudden cardiac
death or are insufficiently accurate to warrant further invasive study or
treatment. The Company believes that its technologies provide a solution to
these shortcomings. The Company's lead product, the CH 2000 System, is designed
to perform conventional cardiac stress tests as well as to incorporate the
Company's proprietary technology to non-invasively measure extremely low levels
of T-wave alternans, a beat-to-beat alternation in a portion of the
electrocardiogram ("ECG" or "EKG"). Clinical research published to date has
demonstrated that T-wave alternans is associated with vulnerability to
ventricular arrhythmias responsible for sudden cardiac death, to a degree
comparable to electrophysiology ("EP") testing, the most accurate invasive
test.
 
  The Company is also conducting research and development on its cardiac
electrical imaging ("CEI") technology for the diagnosis of coronary artery
disease and the detection of acute myocardial infarction. The Company is
evaluating this technology both for incorporation into the CH 2000 System and
for stand-alone use in hospital emergency rooms.
 
  The Company's T-wave alternans and CEI technologies require the use of its
proprietary disposable Hi-Res and Laplacian electrodes, respectively, which the
Company believes will provide a recurring source of revenue. The Company
anticipates that it will be the sole provider of these single-use electrodes
due to their proprietary nature.
 
  The Company owns or is the exclusive licensee of seven patents issued or
allowed and six patents pending in the United States, with 17 corresponding
foreign patents issued or pending with respect to its technology.
 
  The Company's CH 2000 System has received 510(k) clearance from the FDA for
sale in the United States for the purposes of performing standard stress tests
and measuring T-wave alternans. This clearance, however, does not include a
labeling claim covering the applicability or prognostic use
 
                                       3
<PAGE>
 
of the T-wave alternans measurement. The Company is currently conducting
further clinical studies and expects to make a subsequent 510(k) submission in
the first half of 1997 with respect to the prognostic value of the Company's T-
wave alternans technology. The Company has chosen to limit sales of the CH 2000
System in the United States to a limited number of clinical sites until its
proprietary Hi-Res electrodes receive FDA clearance. The Company filed a 510(k)
pre-market notification for the Hi-Res electrodes in May 1996. The CH 2000
System has received the CE mark for sale in Europe, and application has been
made for approval with the Ministry of Health in Japan.
 
  The Company intends to market the CH 2000 System domestically through a
direct sales force and distributors and internationally through distributors.
The Company has entered into agreements with Kontron Instruments Ltd.
("Kontron"), a leading supplier of patient monitoring and cardiac diagnostic
equipment in Europe, for distribution of the CH 2000 System in Europe and the
Middle East, and Fukuda Denshi Co., Ltd. ("Fukuda Denshi"), the leading
supplier of stress test and ECG equipment in Japan, for distribution of the
system in Japan.
 
  The Company was incorporated in Delaware in 1990. The Company's principal
office is located at 1 Oak Park Drive, Bedford, MA 01730 and its telephone
number is (617) 271-1200.
 
  CH 2000(TM) and Hi-Res(TM) are trademarks of the Company. All other trade
names and trademarks appearing in this prospectus are the property of their
respective holders.

                                 RISK FACTORS
 
  An investment in the shares of Common Stock offered hereby involves a high
degree of risk. The following factors, in addition to the other information
contained in this Prospectus, should be carefully considered in evaluating the
Company and its business before purchasing the shares of Common Stock offered
hereby. This Prospectus contains forward-looking statements that involve risks
and uncertainties. The Company's actual results may differ significantly from
the results discussed in the forward-looking statements. Factors that might
cause such differences include those discussed below.
 
DEVELOPMENT STAGE COMPANY; HISTORY OF OPERATING LOSSES
 
  The Company is a development stage company and since inception has engaged
primarily in research, development, testing and obtaining regulatory
clearances for its products. To date, sales of its CH 2000 System have been
limited to participants in clinical trials and the Company's distributor in
Japan. The Company is required to obtain regulatory clearance for significant
aspects of its technology. See "--Uncertainties Relating to Technological
Approaches of the Company" and "--Government Regulation; Future Product
Approvals Uncertain". As of March 31, 1996, the Company had an accumulated
deficit of approximately $5,747,000 and had a net loss of approximately
$2,497,000 for the year ended December 31, 1995. The Company expects to incur
substantial and increasing net losses for the foreseeable future as a result
of sales and marketing, research and product development, manufacturing and
other expenses expected to be incurred as the Company further commercializes
the CH 2000 System and expands its product offerings. There can be no
assurance that the Company will ever generate substantial revenues or achieve
profitability. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations".
 
NO ASSURANCE OF MARKET ACCEPTANCE; SUBSTANTIAL DEPENDENCE ON SINGLE PRODUCT
 
 To date, the Company has developed only one product for commercial sale, the
CH 2000 System, and its other products are at an early stage of development
and significant aspects of the Company's technology are awaiting clearance.
The Company believes that its future success substantially depends upon
successful commercialization and market acceptance of the CH 2000 System
incorporating the Company's T-wave alternans technology. The analysis of T-
wave alternans to diagnose ventricular arrhythmias is a new diagnostic
approach that is currently investigational. The Company has not yet applied
for clearance from the U.S. Food and Drug Administration (the "FDA") for a
labelling claim covering the applicability or prognostic use of its T-wave
alternans technology. In addition, the Company's proprietary Hi-Res
electrodes, which are required for the effective implementation of the CH 2000
System, have not received regulatory clearance. Market acceptance will depend
upon the Company's ability to obtain regulatory clearance or approval for its
Hi-Res electrodes and for claims covering the applicability or prognostic use
of T-wave alternans measurement, as well as its ability to demonstrate the
diagnostic advantages, cost-effectiveness and performance features of the CH
2000 System. Market acceptance will also be driven in large part by acceptance
of the CH 2000 System by influential physicians. There can be no assurance
that the Company will be able to successfully commercialize or achieve market
acceptance of the CH 2000 System or that the Company's competitors will not
develop competing technologies that are superior to those of the Company.
Failure by the Company to successfully commercialize or achieve market
acceptance of the CH 2000 System would have a material adverse effect on the
Company's business, financial condition and results of operations.
 
UNCERTAINTIES RELATING TO TECHNOLOGICAL APPROACHES OF THE COMPANY
 
  The Company intends to develop and sell products which are based upon T-wave
alternans analysis and cardiac electrical imaging technologies that have not
previously been applied to cardiac diagnostic products. There can be no
assurance that a market will develop or that the ultimate size of such market
will justify the Company's significant investment in commercializing its
products. The Company has sponsored and is continuing to sponsor a number of
clinical studies relating to the
 
                                       6
<PAGE>
 
CH 2000 System, its T-wave alternans technology and its Hi-Res electrodes to
establish the prognostic value of its T-wave alternans technology. While these
studies and third-party studies on high risk patients to date have indicated
that T-wave alternans is associated with ventricular arrhythmia to a degree
comparable to EP testing, there can be no assurances that the results of such
studies will continue to do so. Any results of clinical studies or trials
which fail to demonstrate that T-wave alternans is comparable in accuracy to
alternative diagnostic tests, or which otherwise call into question the cost-
effectiveness, efficacy or safety of this, or other Company technologies,
would have a material adverse effect on the Company's business, financial
condition and results of operations. The development of commercial products
based upon these technologies will also be subject to the risks typically
inherent in the development of products based on new technologies. These risks
include the possibility that any diagnostic products based on these
technologies will be found to be ineffective or inaccurate, or otherwise fail
to receive necessary regulatory clearances or approvals; that the proprietary
rights of third parties will preclude the Company or its distributors from
marketing products; or that third parties will market equivalent or superior
products. The Company is currently conducting further clinical studies and
expects to make a subsequent 510(k) submission in the first half of 1997 with
respect to the prognostic value of the Company's T-wave alternans technology.
However, there can be no assurance that the results of such studies will
support such submission or that regulatory clearance will be received. In
addition, there can be no certainty that products incorporating alternative
technologies in which the Company has limited expertise will not be introduced
and adversely affect demand for the Company's products. As a result, there can
be no assurance that the Company's development activities will result in
commercially viable products. Failure to develop commercially viable products
would have a material adverse effect on the Company's business, financial
condition and results of operations.
 
DEPENDENCE UPON LICENSES
 
  The Company and the Massachusetts Institute of Technology ("MIT") have
entered into four license agreements (the "MIT License Agreements"), pursuant
to which the Company is the exclusive licensee of certain technologies upon
which the Company's current and future products are based, including certain
patents associated therewith. These technologies, including the T-wave
alternans analysis technology incorporated in the Company's CH 2000 System,
and technologies relating to cardiac electrical imaging, pacing for the
prevention of cardiac arrhythmias and cardiovascular identification, are of
material importance to the Company. These licenses are exclusive until 2007;
thereafter, each license will convert to a nonexclusive license, and will last
for the life of the applicable patents, unless extension of exclusivity is
agreed to by MIT. In addition, the Company has entered into a license
agreement with Dr. Richard Cohen, a founder, director of, and consultant to,
the Company (the "Cohen License Agreement"), pursuant to which the Company is
the exclusive licensee of certain technology developed by Dr. Cohen which the
Company may include in its future products. These license agreements impose
various commercialization, sublicensing, insurance, royalty, product liability
indemnification and other obligations on the Company. Failure by the Company
to comply with these requirements could result in conversion of the licenses
from being exclusive to nonexclusive in nature or, in some cases, termination
of the license. The loss of the Company's exclusive rights to the technology
licensed under these license agreements or their termination could have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Business--Patents, Trade Secrets and Proprietary
Rights" and "Certain Transactions".
 
GOVERNMENT REGULATION; FUTURE PRODUCT APPROVALS UNCERTAIN
 
  The Company's products, product development activities, manufacturing
processes and sales and marketing are subject to extensive and rigorous
regulation by the FDA and comparable agencies in foreign countries. In the
United States, the FDA regulates the introduction of medical devices as well
as manufacturing, labeling and record keeping procedures for such products. In
order for the Company to market its products for clinical use in the United
States, the Company must obtain from the FDA clearance of a 510(k) pre-market
notification, or approval of a more extensive submission known as pre-market
approval ("PMA") application. The process of obtaining marketing clearance or
approval for
 
                                       7
<PAGE>
 
new medical devices from the FDA can be costly and time consuming, and there
can be no assurance that such clearance or approval will be granted for the
Company's future products on a timely basis, if at all, or that FDA review will
not involve delays that will adversely affect the Company's ability to
commercialize additional products or expand permitted uses of existing
products.
 
  A 510(k) pre-market notification requires the manufacturer of a medical
device to establish that the device is "substantially equivalent" to medical
devices legally marketed in the United States. While the CH 2000 System
currently marketed by the Company, including the Company's T-wave alternans
technology, has received 510(k) clearance from the FDA for sale in the United
States, the 510(k) clearance does not allow the Company to make claims
regarding the effectiveness of this technology in identifying patients at risk
of sudden cardiac death. The Company is currently conducting further clinical
studies and intends to submit a 510(k) application to support such claims. The
Company has also filed a 510(k) pre-market notification for its Hi-Res
electrodes which are required for the effective implementation of the CH 2000
System. For these and any future products, including any product based on the
Company's CEI technology, there can be no assurance that the FDA will concur
with the Company's 510(k) request for clearance, or that the FDA will not
require the Company to file PMA applications. The process of obtaining a PMA
can be more expensive, uncertain and lengthy than the process of obtaining
510(k) clearance, and frequently requires anywhere from one to several years
from the date of submission, if approval is obtained at all. The failure to
obtain 510(k) clearance for additional labeling claims for the CH 2000 System
or for the Hi-Res electrodes would have a material adverse effect on the
business, financial condition and results of operations of the Company.
 
  Even if regulatory clearance to market a device is obtained from the FDA,
this clearance may limit the indicated uses of the device. Marketing clearance
can also be withdrawn by the FDA due to failure to comply with regulatory
standards or the occurrence of unforeseen problems following initial clearance.
The Company may be required to make further filings with the FDA under certain
circumstances such as the addition of new product claims. The FDA could also
limit or prevent the manufacture or distribution of the Company's products and
has the power to require the recall of such products. Significant delay or cost
in obtaining, or failure to obtain FDA clearance to market products, any FDA
limitations on the use of the Company's products, or any withdrawal of
clearance by the FDA could have a material adverse effect on the business,
financial condition and results of operations of the Company.
 
  In addition, all products manufactured by the Company must be manufactured in
compliance with the standards established by the FDA's Good Manufacturing
Practices ("GMP") regulations. Ongoing compliance with GMP and other applicable
regulatory requirements is monitored through periodic inspection by state and
federal agencies, including the FDA. The FDA may inspect the Company and its
facilities from time to time to determine whether the Company is in compliance
with regulations relating to medical device manufacturing companies, including
regulations concerning manufacturing, testing, quality control and product
labeling practices.
 
  FDA regulations depend heavily on administrative interpretation, and there
can be no assurance that future interpretations made by the FDA or other
regulatory bodies, with possible retroactive effect, will not adversely affect
the Company. In addition, changes in the existing regulations or adoption of
new governmental regulations or policies could prevent or delay regulatory
approval of the Company's products.
 
  Failure to comply with applicable regulatory requirements could result in,
among other things, warning letters, fines, injunctions, civil penalties,
recall or seizure of products, total or partial suspension of production,
refusal of the government to grant pre-market clearance or pre-market approval
for devices, withdrawal of approvals and criminal prosecution.
 
  A significant portion of the Company's revenue will be dependent upon sales
of its products outside the United States. Foreign regulatory bodies have
established varying regulations governing product standards, packaging
requirements, labeling requirements, import restrictions, tariff regulations,
duties and tax requirements. Specifically, the European Union ("EU") has
promulgated
 
                                       8
<PAGE>
 
rules which require that medical products receive the right to affix the CE
mark, an international symbol of adherence to quality assurance standards and
compliance with applicable European medical device directives. Although the
Company has obtained CE mark approval for its first product, the CH 2000
System, there is no assurance that the Company will be able to obtain CE
approval for its future products. Application has been made for approval with
the Ministry of Health in Japan, however, there can be no assurance that such
approval will be granted. The inability or failure of the Company or its
international distributors to comply with varying foreign regulations or the
imposition of new regulations could restrict or, in certain countries, result
in the prohibition of the sale of the Company's products internationally and
thereby adversely affect the Company's business, financial condition and
results of operations. See "Business--Government Regulation".
 
RAPID TECHNOLOGICAL CHANGE AND INTENSE COMPETITION
 
  The medical device market is characterized by intensive development efforts
and rapidly advancing technology. The future success of the Company will
depend, in large part, upon its ability to anticipate and keep pace with
advancing technology and competitive innovations. However, there can be no
assurance that the Company will be successful in identifying, developing and
marketing new products or enhancing its existing products. In addition, there
can be no assurance that new products or alternative diagnostic techniques
will not be developed that will render the Company's current or planned
products obsolete or inferior. Rapid technological development by competitors
may result in the Company's products becoming obsolete before the Company
recovers a significant portion of the research, development and
commercialization expenses incurred with respect to such products.
 
  Competition from medical devices which help to diagnose cardiac disease is
intense and likely to increase. The Company competes with manufacturers of ECG
stress tests, the conventional method of diagnosing ischemic heart disease,
and may compete with manufacturers of other non-invasive tests, including
ECGs, Holter monitors, ultrasound tests and systems for measuring cardiac late
potentials. Many of the Company's competitors and potential competitors have
substantially greater capital resources, name recognition, research and
development experience and regulatory, manufacturing and marketing
capabilities. Many of these competitors offer well established, broad product
lines and ancillary services not offered by the Company. Some of the Company's
competitors have long-term or preferential supply arrangements with physicians
and hospitals which may act as a barrier to market entry. In addition, other
large health care companies may enter the non-invasive cardiac diagnosis
product market in the future. Competing companies may succeed in developing
products that are more efficacious or less costly than any that may be
developed by the Company, and such companies also may be more successful than
the Company in producing and marketing such products or their existing
products. Competing companies may also introduce competitive pricing pressures
that may adversely affect the Company's sales levels and margins. There can be
no assurance that the Company will be able to compete successfully with
existing or new competitors. See "Business--Competition".
 
UNCERTAINTY RELATING TO THIRD-PARTY REIMBURSEMENT
 
  The Company could be adversely affected by changes in reimbursement policies
of governmental or private health care payors, particularly to the extent any
such changes affect reimbursement for procedures in which the Company's
products are used. Failure by physicians, hospitals and other users of the
Company's products to obtain sufficient reimbursement from health-care payors
for procedures in which the Company's products are used or adverse changes in
governmental and private third-party payors' policies toward reimbursement for
such procedures would have a material adverse effect on the Company's
business, financial condition and results of operations.
 
  If the Company obtains the necessary foreign regulatory approvals, market
acceptance of the Company's products in international markets would be
dependent, in part, upon the availability of
 
                                       9
<PAGE>
 
reimbursement within prevailing health-care payment systems. Reimbursement and
health-care payment systems in international markets vary significantly by
country, and include both government sponsored health care and private
insurance. The Company intends to seek international reimbursement approvals,
although there can be no assurance that any such approvals will be obtained in
a timely manner, if at all, and failure to receive international reimbursement
approvals could have an adverse effect on market acceptance of the Company's
products in the international markets in which such approvals are sought. See
"Business--Reimbursement".
 
UNCERTAINTY REGARDING PATENTS AND PROPRIETARY RIGHTS
 
  The computer algorithms that allow the CH 2000 System to measure T-wave
alternans and certain aspects of the Company's CEI technology, including its
CEI electrodes, are covered by U.S. patents issued to MIT that are licensed
exclusively to the Company. The Company has applied for a U.S. patent covering
the use of exercise or physiological stress in the measurement of T-wave
alternans, which has been allowed, and corresponding foreign patents are
pending. The Company has also applied for U.S. and foreign patents covering
additional proprietary signal processing algorithms and its Hi-Res electrodes
for use in the measurement of T-wave alternans. The Company owns or is the
exclusive licensee of seven patents issued or allowed and six patents pending
in the United States, with 17 corresponding foreign patents issued or pending
with respect to its technololgy. The MIT License Agreement and the Cohen
License Agreement impose various commercialization, sublicensing, insurance,
royalty, product liability indemnification and other obligations on the
Company. See "-- Dependence Upon Licenses".
 
  The Company's future success will depend, in part, on its ability to
continue to develop patentable products, enforce its patents and obtain patent
protection for its products both in the United States and in other countries.
However, the patent positions of medical device companies, including the
Company, are generally uncertain and involve complex legal and factual
questions. No assurance can be given that patents will issue from any patent
applications owned by or licensed to the Company or that, if patents do issue,
the claims allowed will be sufficiently broad to protect the Company's
technology. In addition, no assurance can be given that any issued patents
owned by or licensed to the Company will not be challenged, invalidated or
circumvented, or that the rights granted thereunder will provide competitive
advantages to the Company.
 
  The medical device industry has been characterized by extensive litigation
regarding patents and other intellectual property rights. Litigation, which is
likely to result in substantial expense to the Company, may be necessary to
enforce any patents issued or licensed to the Company and/or to determine the
scope and validity of others' proprietary rights. The Company may also have to
participate in interference proceedings declared by the United States Patent
and Trademark Office, which could result in substantial expense to the
Company, to determine the priority of inventions. Furthermore, the Company may
have to participate at substantial cost in International Trade Commission
proceedings to abate importation of products which would compete unfairly with
products of the Company.
 
  The Company relies on unpatented trade secrets to protect its proprietary
technology, and no assurance can be given that others will not independently
develop or otherwise acquire substantially equivalent techniques or otherwise
gain access to the Company's proprietary technology or disclose such
technology or that the Company can ultimately protect its rights to such
unpatented proprietary technology. The Company also relies on confidentiality
agreements with its collaborators, employees, advisors, vendors and
consultants to protect its proprietary technology. There can be no assurance
that these agreements will not be breached, that the Company would have
adequate remedies for any breach or that the Company's trade secrets will not
otherwise become known or be independently developed by competitors. Failure
to obtain or maintain patent and trade secret protection, for any reason,
could have a material adverse effect on the Company's business, financial
condition and results of operations. See "Business--Patents, Trade Secrets and
Proprietary Rights".
 
                                      10
<PAGE>
 
LIMITED MANUFACTURING AND MARKETING EXPERIENCE
 
  For the Company to commercialize its products successfully, it must
manufacture or assemble these products, either by itself or through third
parties, in commercial quantities, at high quality levels and at commercially
reasonable costs. Such manufacturing or assembly must be accomplished in
accordance with GMP and, by 1998, ISO 9001 and other applicable regulatory
requirements. There can be no assurance that the Company's reliance on others
for the manufacture of its components, including the Hi-Res electrodes, will
not result in problems with product supply. Interruptions in the availability
of components could delay or prevent the development and commercial marketing
of the CH 2000 System.
 
  The Company intends to market its products in the United States primarily
through its own direct sales force and, to a lesser extent, distributors.
Significant expenditures, management resources and time will be required for
the Company to develop a successful domestic direct sales force. There can be
no assurance that the Company will be able to recruit and retain skilled sales
management, direct salespersons or distributors, or that the Company's sales
efforts will be successful. See "Business--Sales and Marketing". The Company
intends to market its products internationally through independent
distributors. These distributors may also distribute competing products under
certain circumstances. The loss of a significant international distributor
could have a material adverse effect on the Company's business if a new
distributor, sales representative or other suitable sales organization cannot
be found on a timely basis in the relevant geographic market. To the extent
that the Company relies on sales in certain territories through distributors,
any revenues the Company receives in those territories will depend upon the
efforts of its distributors. Furthermore, there can be no assurance that a
distributor will market the Company's products successfully or that the terms
of its distribution arrangements will be acceptable to the Company. See
"Business--Sales and Marketing".
 
DEPENDENCE UPON KEY SUPPLIERS
 
  Although the Company believes that there are a number of qualified vendors
for most of the components and subassemblies required for its products,
certain components are currently single sourced. Moreover, substitute
components may not be immediately available in quantities needed by the
Company. Delays associated with any future component shortages, particularly
as the Company scales up its manufacturing activities in support of commercial
sales, could have a material adverse effect on the Company's business,
financial condition and results of operations. The Company is actively seeking
alternative sources but the Company's inability to obtain alternative
suppliers or a sufficient quantity of such components on favorable terms could
materially adversely affect the Company's business, financial condition and
results of operations. See "Business--Manufacturing".
 
ATTRACTION AND RETENTION OF KEY MANAGEMENT PERSONNEL AND CONSULTANTS
 
  The Company is highly dependent on its senior management, marketing and
technical personnel, the loss of whose services could have a material adverse
effect on the Company. Recruiting and retaining such personnel in the future
will be critical to the Company's success. There can be no assurance that the
Company will be able to attract and retain qualified personnel on acceptable
terms given the competition for such qualified personnel.
 
  The Company is party to a consulting agreement with Dr. Cohen, pursuant to
which Dr. Cohen has agreed to provide one day a week of consulting services to
the Company through February 1998 regarding development and commercialization
of the Company's core technologies which have been licensed from MIT. During
the term of the consulting agreement, and for a period of up to two additional
years following its termination or expiration, Dr. Cohen is obligated not to
compete with the Company provided the Company makes continuing payments to Dr.
Cohen during such two year period. In the event that Dr. Cohen ceases to
provide consulting services or to maintain a relationship with the Company,
whether by reason of expiration of the consulting agreement, a breach by the
Company of
 
                                      11
<PAGE>
 
the agreement's terms, or any dispute between the Company and Dr. Cohen, such
cessation would have a material adverse impact upon the Company in view of Dr.
Cohen's reputation with important clinical constituencies, and his expertise
concerning the Company's technologies.
 
  In addition, the Company depends on other third party consultants,
collaborators and contractors in connection with its product development,
testing and manufacturing activities. The discontinuation of the Company's
collaborative relationship with any of its consultants, collaborators or
contractors, or the Company's failure to establish relationships in the future
with highly qualified collaborators, consultants or contractors, could have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
  The Company has entered into employment agreements with Jeffrey M. Arnold,
the Company's President and Chief Executive Officer, and Dr. Paul Albrecht,
Vice President of Engineering. See "Management--Employment Agreements". In
addition, the Company maintains life insurance policies for its benefit on the
lives of Dr. Cohen and Mr. Arnold in the amounts of $2.0 million and $1.0
million, respectively.
 
INTERNATIONAL SALES AND OPERATIONS RISKS
 
  The Company plans to sell the CH 2000 System and any future products on a
worldwide basis. A number of risks are inherent in international transactions.
International sales and operations may be limited or disrupted by the
imposition of government controls, export license requirements, political
instability, trade restrictions, changes in tariffs or difficulties in
staffing and managing international operations. In addition, laws in foreign
countries may not always provide protection for the Company's proprietary
rights in its technologies. Foreign regulatory agencies often establish
product standards different from those in the United States and any inability
to obtain foreign regulatory approvals on a timely basis could have an adverse
effect on the Company's international business and its financial condition and
results of operations. Additionally, the Company's business, financial
condition and results of operations may be adversely affected by fluctuations
in currency exchange rates as well as increases in duty rates and difficulties
in obtaining export licenses. There can be no assurance that the Company will
be able to successfully commercialize the CH 2000 System or any future product
in any foreign market. See "Business--Marketing and Sales".
 
FUTURE CAPITAL NEEDS; UNCERTAINTY OF ADDITIONAL FUNDING
 
  The Company believes that its existing capital resources, together with the
proceeds of this Offering and interest earned thereon, will be adequate to
satisfy its capital requirements for at least the next two years. The
Company's future capital requirements will depend, however, on many factors,
including sales of its existing product, the continued progress in, and
magnitude of, its research and product development programs, the timing and
costs involved in obtaining regulatory approvals, the costs involved in
filing, prosecuting, enforcing and defending patent claims, competing
technological and market developments and the costs and success of
commercialization activities, and there can be no assurance that the Company
may not in the future require additional funding. If the Company requires
additional funding, there can be no assurance that it will be able to obtain
such funding on acceptable terms, if at all.
 
PRODUCT LIABILITY RISK; LIMITED INSURANCE COVERAGE
 
  The manufacture and sale of medical devices entails significant risk of
product liability claims in the event that the use of such devices is alleged
to have resulted in adverse effects to a patient. The Company has taken and
will continue to take what it believes are appropriate precautions, including
maintaining general liability and commercial liability insurance policies
which include coverage for product liability claims. The limit under these
policies totals $2.0 million. However, there can be no
 
                                      12
<PAGE>
 
assurance that the Company's existing insurance coverage limits are adequate
to protect the Company from any liabilities it might incur in connection with
the sale of its products. In addition, the Company may require increased
product liability coverage. Such insurance is expensive and in the future may
not be available on acceptable terms, if at all. A successful product
liability claim or series of claims brought against the Company in excess of
its insurance coverage could have a material adverse effect on the Company's
business, financial condition and results of operations. Additionally, it is
possible that adverse product liability actions could negatively affect the
Company's ability to obtain and maintain regulatory approval for its products.
 
NO PUBLIC MARKET; POSSIBLE VOLATILITY OF SHARE PRICE
 
  Prior to this Offering, there has been no public market for the Common Stock
of the Company, and there can be no assurance that an active trading market
will develop or be sustained after this Offering. The initial public offering
price will be determined by negotiations among the Company and the
representatives of the Underwriters based upon several factors and may not be
indicative of future market prices. See "Underwriting" for a discussion of the
factors to be considered in determining the initial public offering price. The
market price of the Company's Common Stock could be subject to wide
fluctuations in response to quarterly variations in the Company's operating
results, announcements of technological innovations or new commercial products
by the Company or its competitors, governmental regulation, developments in
patent or other proprietary rights and public concern regarding the safety,
effectiveness or other implications of the products being developed by the
Company. In addition, the stock market has experienced extreme price and
volume fluctuations. This volatility has significantly affected the market
prices of securities of many medical device companies for reasons frequently
unrelated to or disproportionate to the operating performance of the specific
companies. These broad market fluctuations may adversely affect the market
price of the Company's Common Stock.
 
CONTROL BY DIRECTORS, OFFICERS AND PRINCIPAL STOCKHOLDERS
 
  Upon completion of this Offering, the Company's directors, executive
officers and principal stockholders, together with their affiliates, will
beneficially own approximately 47% of the Company's outstanding Common Stock
(approximately 45% if the Underwriters exercise their over-allotment option in
full). As a result, these stockholders, if acting together, will have the
ability to influence the outcome of corporate actions requiring stockholder
approval, including the election of directors and the approval of certain
mergers and other significant corporate transactions, such as a sale of
substantially all of the Company's assets, irrespective of how other
stockholders of the Company may vote. This concentration of ownership may have
the effect of delaying or preventing a change in control of the Company. See
"Management" and "Principal Stockholders".
 
SHARES ELIGIBLE FOR FUTURE SALE
 
  Sales of substantial amounts of Common Stock in the public market following
this Offering could have a material adverse effect on the market price of the
Common Stock. The 3,000,000 shares of Common Stock offered by the Company (and
any shares sold pursuant to the exercise of the Underwriters' over-allotment
option) will be freely tradable without restriction. An additional 225,028
shares of Common Stock, which are not subject to lock-up agreements with the
Underwriters, will be eligible for sale in the public market upon the date of
this Prospectus in reliance on Rule 144(k) under the Securities Act of 1933 as
amended (the "Securities Act"). An additional 1,832,864 shares of Common
Stock, which are not subject to lock-up agreements with the Underwriters, will
be eligible for sale in the public market on October 25, 1996, in reliance on
Rule 144(k) under the Securities Act. Beginning approximately 90 days after
the date of this Prospectus, approximately 4,930,147 additional
 
                                      13
<PAGE>
 
shares of Common Stock (including approximately 542,960 shares of Common Stock
issuable upon exercise of vested stock options) will become eligible for sale
in the public market pursuant to Rules 144 and 701. Additionally, stockholders
of the Company owning an aggregate of approximately 5,675,205 shares of Common
Stock, have the right to demand registration under the Securities Act of their
shares of Common Stock and have the right to have their shares of Common Stock
included in future registered public offerings of securities by the Company.
The Company cannot predict the effect, if any, that market sales of shares or
the availability of shares for sale will have on the market price of the
Common Stock prevailing from time to time. Sales of significant amounts of the
Common Stock of the Company in the public market could adversely affect the
market price of the Company's Common Stock and could impair the Company's
ability to raise capital through an offering of its equity securities. See
"Description of Capital Stock--Common Stock", "Shares Eligible for Future
Sale" and "Underwriting".
 
ANTI-TAKEOVER PROVISIONS
 
  The Company's Restated Certificate of Incorporation as in effect upon the
closing of this Offering will require that any action required or permitted to
be taken by stockholders of the Company must be effected at a duly called
annual or special meeting of stockholders and may not be effected by any
consent in writing, and will require reasonable advance notice by a
stockholder of a proposal or director nomination which such stockholder
desires to present at any annual or special meeting of stockholders. Special
meetings of stockholders may be called only by the President of the Company or
by the Board of Directors. The Restated Certificate of Incorporation provides
for a classified Board of Directors, and members of the Board of Directors may
be removed only for cause upon the affirmative vote of holders of at least
two-thirds of the shares of capital stock of the Company entitled to vote. In
addition, the Board of Directors will have the authority, without further
action by the stockholders, to fix the rights and preferences of, and issue
shares of, Preferred Stock. These provisions and other provisions of the
Restated Certificate of Incorporation, may have the effect of deterring
unsolicited acquisition proposals or hostile takeovers or delaying or
preventing changes in control or management of the Company, including
transactions in which stockholders might otherwise receive a premium for their
shares over the then current market prices. In addition, these provisions may
limit the ability of stockholders to approve transactions that they may deem
to be in their best interests. See "Description of Capital Stock--Preferred
Stock" and "--Delaware Law and Certain Charter and By-Law Provisions".
 
SIGNIFICANT FLEXIBILITY IN APPLYING NET PROCEEDS OF OFFERING
 
  Currently, the Company has no specific plans for the net proceeds of this
Offering, other than to fund research and development activities, clinical
studies, capital equipment for manufacturing scale-up, sales and marketing,
and for working capital and general corporate purposes. In addition to
obtaining equity capital, the purpose of this Offering is to create a public
market for the Common Stock and to facilitate future access to public markets.
A portion of the net proceeds may also be used for the acquisition of products
and technologies that are complementary to those of the Company. Accordingly,
management will have significant flexibility in applying the net proceeds of
this Offering. See "Use of Proceeds".
 
ABSENCE OF DIVIDENDS
 
  The Company has not paid any dividends on the Common Stock since its
inception and does not anticipate paying any dividends in the future.
Declaration of dividends on the Common Stock will depend upon, among other
things, future earnings, if any, the operating and financial condition of the
Company, its capital requirements and general business conditions. See
"Dividend Policy".

<PAGE>
 
                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of the 3,000,000 shares of
Common Stock offered hereby are estimated to be $32.9 million ($37.9 million
if the Underwriters exercise their over-allotment option in full), assuming an
initial public offering price of $12.00 per share and after deducting the
underwriting discount and estimated offering expenses payable by the Company.
 
  The Company intends to use the net proceeds of this Offering to fund
research and development, clinical studies, the acquisition of capital
equipment for manufacturing scale-up, sales and marketing activities and for
working capital and general corporate purposes. A portion of the net proceeds
may also be used for the acquisition of products and technologies that are
complementary to those of the Company.
 
  The amount and timing of expenditures may vary significantly depending upon
numerous factors, including the success of the Company's currently marketed
product, the continued progress in, and magnitude of the Company's research
and product development programs, market acceptance of the Company's products,
the timing and costs involved in obtaining regulatory clearances and
approvals, the costs involved in filing, prosecuting, enforcing and defending
patent claims, and competing technological and market developments and the
costs and success of its commercialization activities. Based upon its current
operating plan, the Company believes that its existing capital resources,
together with the proceeds of this Offering and interest earned thereon, will
be adequate to satisfy its capital requirements for at least the next two
years.
 
  Pending application of the proceeds of this Offering as described above, the
Company intends to invest the net proceeds of this Offering in short-term,
investment-grade, interest-bearing instruments. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations".
 
                                DIVIDEND POLICY
 
  The Company has never declared or paid any cash dividends on its capital
stock. The Company currently intends to retain future earnings, if any, for
use in its business and therefore does not anticipate paying cash dividends in
the foreseeable future. Payment of future dividends, if any, will be at the
discretion of the Company's Board of Directors after taking into account
various factors, including the Company's financial condition, operating
results, current and anticipated cash needs and plans for expansion. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources".

Company giving effect to the conversion of all outstanding shares of Preferred
Stock into Common Stock at the closing of this Offering, and (iii) the pro
forma capitalization and cash position of the Company as adjusted to reflect
the issuance and sale of 3,000,000 shares of Common Stock offered hereby at an
assumed initial public offering price of $12.00 per share and the application

estimated offering expenses.

(1) The foregoing assumes no exercise of outstanding options or warrants. As
    of March 31, 1996, there were outstanding options to purchase 1,319,499
    shares of Common Stock under the Company's 1993 Incentive and Non-
    Qualified Stock Option Plan (the "1993 Plan") at a weighted average
    exercise price of $0.54 per share, and warrants to purchase 438,538 shares
    of Common Stock at an exercise price of $2.00 per share. As of the closing
    of this Offering, an additional 1,200,000 shares will be reserved for
    future issuance under the Company's stock plans. See "Management--Employee
    Benefit Plans" and Notes 5 and 6 to the Company's financial statements.

                                   DILUTION
 
  The pro forma net tangible book value of the Company as of March 31, 1996
was approximately $3,353,000, or $0.44 per share, after giving effect to the
conversion of all outstanding shares of Preferred Stock into an aggregate of
4,455,708 shares of Common Stock upon completion of this Offering. Pro forma
net tangible book value per share represents the amount of total tangible
assets of the Company reduced by the Company's total liabilities, divided by
the number of shares of Common Stock outstanding. Assuming an offering price
of $12.00 per share and after giving effect to the sale by the Company of
3,000,000 shares of Common Stock in this Offering (after deducting the
estimated underwriting discount and offering expenses), the pro forma net
tangible book value of the Company as of March 31, 1996 would have been
approximately $36,208,000 or $3.40 per share. This represents an immediate
increase in pro forma net tangible book value of $2.96 per share to existing
stockholders and an immediate dilution in pro forma net tangible book value of
$8.60 per share to new investors purchasing Common Stock in this Offering. The
following table illustrates the per share dilution:

  The above computation assumes no exercise of outstanding options and
warrants since March 31, 1996. As of March 31, 1996, there were options and
warrants outstanding to purchase an aggregate of 1,758,037 shares of Common
Stock at a weighted average exercise price of $0.90 per share. The exercise of
such options and warrants will result in further dilution to new investors. As
of the closing of this Offering, an additional 1,200,000 shares of Common
Stock will be reserved for future issuance under the Company's stock plans.

- -------
(1) The Company's operations during the period from inception (January 16,
    1990) through December 31, 1992 were minimal, consisting primarily of
    business establishment and planning. During the period from inception
    (January 16, 1990) through December 31, 1991, the Company's only activity
    consisted of incorporation and the sale of 50 shares of its Common Stock
    for an aggregate of $1. No expenses were recorded during this period.
    During the year ended December 31, 1992, the Company's activities were
    comprised of initial start up expenses totalling $41,888 (current
    liabilities related to these expenses totaled $37,310 at December 31,
    1992) and the issuance of additional Common Stock for cash proceeds of
    $5,599. Due to the immaterial nature of these activities, the statement of
    operations data for the years ended December 31, 1991 and 1992, and
    balance sheet data as of December 31, 1991 and 1992 have been omitted from
    the table above. See the Company's financial statements and related notes
    thereto included elsewhere in this Prospectus.
(2) For the year ended December 31, 1995 and the three months ended March 31,
    1996, pro forma weighted average common and common equivalent shares
    outstanding consist of 7,233,875 and 7,619,861 shares of Common Stock,
    respectively, after giving effect to the reverse stock split and the
    conversion of preferred stock upon the completion of the Offering and
    including 330,233 and 319,011 shares, respectively, attributable to
    options granted in the twelve month period prior to the Offering using the

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
  Cambridge Heart is engaged in the research, development and
commercialization of products for the non-invasive diagnosis of cardiac
disease. The Company has generated limited revenues from the shipment of
demonstration units of its first product and has experienced substantial net
losses since its inception, and expects to incur substantial and increasing
net losses for the foreseeable future. The Company believes that its research
and development expenses will increase significantly in the future as it
develops additional products and funds clinical trials of its products. The
Company's research and development expenses may also increase in the future as
it supplements its internal research and development with third party
technology licenses and potential product acquisitions. The Company also
expects that its selling, general and administrative expenses will continue to
increase in connection with the Company's continued expansion of its sales and
marketing activities. Revenues generated from the sale of the Company's
products will depend upon numerous factors, including the timing of regulatory
actions, progress of product development, the extent to which the Company's
products gain market acceptance, varying pricing promotions and volume
discounts to customers, competition and the availability of third party
reimbursement. The Company has incurred cumulative net losses since inception
through March 31, 1996 of approximately $5,747,000. See "Risk Factors--
Development Stage Company; History of Operating Losses".
 
RESULTS OF OPERATIONS
 
QUARTERS ENDED MARCH 31, 1995 AND 1996
 
  The Company had no product revenue in the quarter ended March 31, 1995 and
product revenue of $55,000 in the quarter ended March 31, 1996. This revenue
resulted from the shipment of demonstration units of the CH 2000 System in the
United States.
 
  Cost of goods sold was $49,000 for the quarter ended March 31, 1996,
representing 89% of product sales. These expenses reflect a number of fixed
costs that were incurred as the Company expanded manufacturing operations in
anticipation of commercializing its products.
 
  The Company's research and development expenses were $414,000 in the quarter
ended March 31, 1995 and $353,000 in the quarter ended March 31, 1996. The
expenses for 1995 included prototype CH 2000 Systems for clinical sites.
 
  The Company's selling, general and administrative expenses increased from
$191,000 in the quarter ended March 31, 1995 to $366,000 in the quarter ended
March 31, 1996. The increase was primarily attributable to the development of
the Company's administrative infrastructure.
 
  Interest income was $44,000 in the quarter ended March 31, 1995, compared to
$47,000 in the quarter ended March 31, 1996.
 
YEARS ENDED DECEMBER 31, 1993, 1994 AND 1995
 
  The Company recorded its first product revenue of $68,000 in 1995. This
revenue resulted from the shipment of demonstration units of the CH 2000
System to Fukuda Denshi, the Company's distributor in Japan. In 1994, the
Company recognized revenue of $25,000 in connection with a research and option
agreement with a third party. See "Business--Research and Development".
 
  Cost of goods sold was $141,000 in 1995, representing 208% of product sales
in 1995. These expenses reflect a number of fixed costs that were incurred as
the Company expanded manufacturing operations in anticipation of
commercializing its products.
 
 
                                      19
<PAGE>
 
  The Company's research and development expenses were $589,000 in 1993,
$1,124,000 in 1994 and $1,560,000 in 1995. Research and development expenses
have primarily related to product development expenses for the CH 2000 System
which the Company first introduced in the third quarter of 1995. In 1995, the
Company's research and development expenses also included expenses relating to
the development of its proprietary Hi-Res electrodes. The increase in research
and development expenses in 1995 from 1994 was attributable primarily to
increases in personnel and clinical studies support.
 
  The Company's selling, general and administrative expenses increased from
$321,000 in 1993, to $724,000 in 1994 and $1,110,000 in 1995. The increases in
1994 and 1995 were primarily attributable to the development of the Company's
administrative infrastructure.
 
  Interest income was $33,000 in 1993, $164,000 in 1994 and $246,000 in 1995.
The changes in interest income from year to year reflect fluctuations in
interest rates in each of these years as well as an increased cash balance
resulting from the sale of convertible preferred stock in 1993 and 1995. See
"--Liquidity and Capital Resources".
 
  Inflation did not have a significant effect on the Company's results of
operations for any of the three years in the period ended December 31, 1995.
 
  The Company recorded no provision for income taxes for 1993, 1994 and 1995
because it incurred net losses in each of such years. At December 31, 1995,
the Company had net operating loss carryforwards of $4,871,000 as well as
$237,000 of tax credit carryforwards available to offset future taxable income
and income tax liabilities, respectively. These carryforwards generally expire
in the years 2007 through 2010 and may be subject to annual limitations as a
result of changes in the Company's ownership. There can be no assurance that
changes in ownership in future periods or continuing losses will not
significantly limit the Company's use of net operating loss and tax credit
carryforwards.
 
  The Company has generated taxable losses from operations since inception
and, accordingly, has no taxable income available to offset the carryback of
net operating losses. In addition, although management's operating plans
anticipate taxable income in future periods, such plans provide for taxable
losses over the near term and make significant assumptions which cannot be
reasonably assured including approval of the Company's products by the FDA and
market acceptance of these products by customers. Based upon the weight of all
available evidence, the Company has provided a full valuation allowance
($2,200,000 at December 31, 1995) for its deferred tax assets since, in the
opinion of management, realization of these future benefits is not
sufficiently assured (defined as a likelihood of slightly more than 50
percent).
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Since inception, the Company has financed operations primarily from the sale
of convertible preferred stock. As of March 31, 1996, the Company had raised
$9,065,000 (net of stock issuance costs) from the sales of equity securities,
with net proceeds of $5,697,000 received in 1993 and $3,353,000 received in
1995.
 
  As of March 31, 1996, the Company had cash and cash equivalents of
$3,027,000. The proceeds of the equity offerings have been used primarily to
fund operating losses of $5,747,000, reflecting expenditures made primarily to
support research and development activities, to form a marketing and sales
organization, to support an administrative infrastructure, and the investment
of approximately $250,000 in property and equipment as of March 31, 1996. In
1995, the Company used $2,615,000 to fund operating activities.
 
  The Company expects its capital expenditures to increase as it continues to
commercialize its products, particularly in connection with the manufacture of
its proprietary Hi-Res electrodes. The Company does not expect capital
expenditures to exceed an aggregate $3,000,000 over the next two years.
 
                                      20
<PAGE>
 
  The Company anticipates that its existing capital resources, together with
the proceeds of this Offering and the interest earned thereon, will be
adequate to satisfy its capital requirements for at least the next two years.
There may be circumstances, however, that would accelerate the Company's use
of proceeds from this Offering. If this occurs, the Company, may, from time to
time, incur additional indebtedness or issue, in public or private
transactions, equity or debt securities. However, there can be no assurance
that suitable debt or equity financing will be available to the Company on
acceptable terms, if at all.
 
RECENTLY ENACTED ACCOUNTING STANDARDS
 
  In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 123, "Accounting for Stock-based
Compensation". The Company has elected to adopt this standard in 1996 through
footnote disclosure only.

                                   BUSINESS
 
  Cambridge Heart is engaged in the research, development and
commercialization of products for the non-invasive diagnosis of cardiac
disease. Using innovative technologies, including proprietary disposable
electrodes, the Company is addressing such key problems in cardiac diagnosis
as (i) the identification of those at risk of sudden cardiac death, accounting
for approximately 50% of all deaths due to heart attack, (ii) the early
detection of coronary artery disease and (iii) the prompt and accurate
diagnosis of heart attack. The Company's lead product, the CH 2000 System, is
designed to perform conventional cardiac stress tests as well as to
incorporate the Company's proprietary technology to non-invasively measure
extremely low levels of T-wave alternans, a beat-to-beat alternation in a
portion of the electrocardiogram. Clinical research published to date has
demonstrated that T-wave alternans is associated with vulnerability to
ventricular arrhythmias responsible for sudden cardiac death to a degree
comparable to EP testing, the most accurate invasive test.
 
 
HEART DISEASE
 
  Cardiac disease is the leading cause of death in the United States and many
other developed countries. According to the American Heart Association, in
1993 cardiovascular disease accounted for 42% of all deaths in the United
States. Approximately 1.5 million people suffered heart attacks in the United
States in 1993, resulting in 500,000 deaths. Approximately half of these
deaths were sudden, generally the result of ventricular arrhythmias, which
cause the heart to beat in an abnormal and ineffective manner.
 
 ISCHEMIC HEART DISEASE AND ACUTE MYOCARDIAL INFARCTION
 
  Disease Characteristics. Ischemic heart disease, also referred to as
coronary artery disease, is related to the progressive narrowing of the blood
vessels that supply oxygen and nutrients to the heart. When blood flow becomes
inadequate, the patient may experience chest pain (angina), especially under
conditions of stress or exercise. When the build-up of plaque or the presence
of a blood clot further narrows the coronary arteries, an area of the heart
muscle (myocardium) may die, an event called a myocardial infarction, the most
common cause of heart attack.
 
  Disease Incidence.  Coronary artery disease is a common form of cardiac
disease, affecting approximately 13.5 million people in the United States. It
is estimated that approximately eight million patients each year present
themselves at emergency rooms in the United States with acute chest pain or
other symptoms typical of acute myocardial infarction. Of these patients,
approximately 2.7 million are admitted to the hospital for evaluation, of whom
about 1 million actually have experienced a myocardial infarction. Despite
this high admission rate, it has been estimated that between 4% and 8% of
those patients experiencing myocardial infarction may be sent home
inappropriately, some of whom die soon thereafter.
 
  Current Therapies.  If properly diagnosed, ischemic heart disease is
treatable with coronary artery bypass grafting ("CABG") or coronary
("balloon") angioplasty. These are used to bypass, reopen or widen blocked or
narrowed arteries, or with medication (such as nitrates, beta blockers and
calcium channel blockers), which are used to improve blood flow or regulate
the heart. In 1993, an estimated 485,000 CABG procedures and 398,000
angioplasty procedures were performed in the United States.
 
  Current Diagnostic Procedures.  The principal non-invasive diagnostic tools
utilized in the diagnosis of ischemic heart disease are the ECG and the
exercise stress test. Normal heartbeats make a specific pattern of electrical
signals that can be measured by an ECG through electrodes applied to the
patient and recorded graphically on paper or displayed on a video monitor.
Specific types of heart disease usually change the pattern of signals in ways
recognizable to a physician.
 
                                      22
<PAGE>
 
  Most patients with suspected heart disease undergo an exercise stress test,
during which the patient exercises on a motorized treadmill or bicycle
ergometer with ECG electrodes attached to the patient's chest. Although
standard stress tests are widely used as a screening test for heart disease,
stress tests are not considered to be highly sensitive or accurate in
detecting or localizing coronary artery blockages. For example, these tests
generally have a false negative rate on the order of 34%, and, in the absence
of chest pain, as high as 63%. This lack of accuracy may result in unnecessary
follow-on procedures or in the failure to detect significant heart disease.
 
  The accuracy of stress tests and the ability to locate coronary artery
disease may be enhanced by the use of ultrasound imaging technology (an
"echocardiogram"), or through the use of a low level radioactive tracer
isotope (a "nuclear stress test"). Both of these tests are considered to be
more sensitive in detecting and analyzing coronary artery blockages than a
standard treadmill exercise test, but are also substantially more expensive.
 
  There were approximately six million standard exercise ECG stress tests
performed in the United States in 1995 at a cost of $200 to $350 per
procedure. In addition, there were an estimated 1.5 million echocardiogram
stress tests performed at a cost of $800 to $1,000 per procedure and 1.5
million nuclear stress tests performed at a cost of $1,000 to $1,500 per
procedure.
 
  Patients with a positive stress test or with suspected coronary artery
disease will generally undergo invasive coronary angiography. In this
procedure, a catheter is inserted through an artery in the leg or arm and
guided into the patient's coronary arteries, where the physician can use the
catheter to diagnose the nature and extent of the patient's coronary artery
disease. In 1993, approximately 1.5 million coronary angiographies were
performed in the United States at a cost of approximately $3,000 to $4,000 per
procedure.
 
 VENTRICULAR ARRHYTHMIA AND SUDDEN CARDIAC DEATH
 
  Disease Characteristics. Arrhythmias are abnormalities in the regular
beating pattern of the heart caused by an alteration in the normal pattern of
conduction of electrical signals within the heart. Sudden cardiac arrest is
generally caused by ventricular fibrillation, a disorganized quivering of the
ventricles which interferes with the pumping action of the heart, or by
ventricular tachycardia, a rapid beating of the ventricles which can
degenerate into ventricular fibrillation. Ventricular fibrillation and
ventricular tachycardia most often result from the triggering of an underlying
electrical instability of the heart. This electrical instability may be the
result of congenital factors, may be caused by scar tissue from a previous
myocardial infarction, or may result from coronary artery disease or other
diseases.
 
  Disease Incidence. Each year more than 300,000 individuals in the United
States experience a sudden cardiac arrest episode. Of these, approximately
250,000 individuals die and 50,000 individuals survive, primarily through
emergency defibrillation. Most of those who die suddenly have some pre-
identified condition which puts them at elevated risk. For example, without
treatment, the approximately 50,000 annual survivors of a cardiac arrest
episode have over a 25% chance of dying suddenly in the one year following
cardiac arrest. Of the approximately 1.0 million annual survivors of
myocardial infarction, 13% of men and 6% of women will die suddenly in the
following six years. Patients with enlarged hearts due to hypertrophic
cardiomyopathy (approximately 500,000 patients), patients with congestive
heart failure (approximately 4.7 million patients), patients with known
coronary artery disease (approximately 13.5 million patients) and patients who
have experienced fainting spells are also at elevated risk. Such high risk
subgroups account for approximately 75% of sudden cardiac deaths; for the
other 25% there is no prior indication of cardiac disease.
 
 
                                      23
<PAGE>
 
  Current Therapies. When properly diagnosed, those patients at risk of sudden
cardiac death are treatable with an implantable cardioverter defibrillator
("ICD"), with RF ablation of abnormal tissue in the ventricles, which can
improve electrical conduction in the heart, or with anti-arrhythmic
medication. In the United States, most patients are treated with an ICD, an
electronic device similar to a pacemaker that is permanently implanted in the
patient. The ICD is designed to monitor the patient's heartbeat and, in the
event of ventricular fibrillation or ventricular tachycardia, to deliver
electric pulses or shocks to the heart to terminate the arrhythmia. It is
estimated that 21,000 ICDs were implanted in 1995 in the United States.
 
  Current Diagnostic Procedures. Patients believed to be at risk of
ventricular arrhythmia may undergo an invasive EP study. Diagnostic EP studies
involve the deliberate electric stimulation of the heart utilizing specially-
designed catheters. These catheters are inserted into the heart through a
major vein or artery to provoke heart rhythm disturbances which, if they
occur, are then terminated by pacing or defibrillation shocks. Patients in
whom certain types of ventricular arrhythmia can be induced via this procedure
are considered to be at risk of sudden cardiac death.
 
  Although EP studies are generally effective in diagnosing cardiac
arrhythmias, they are invasive and costly procedures. As a result, their use
is generally limited to patients who have demonstrated previous episodes of
ventricular arrhythmia, or have experienced fainting spells believed to be
caused by these arrhythmias. It is estimated that approximately 75,000 EP
studies were performed for the diagnosis of ventricular arrhythmias in 1995 in
the United States at a cost of $3,000 to $4,000 per procedure. This represents
a small fraction of the many millions of persons believed to be at risk but
who are not studied or treated because of the lack of an effective non-
invasive screening test.
 
  The Company believes that, aside from its technology, there is no effective
non-invasive diagnostic test to assess accurately the risk of sudden cardiac
death caused by ventricular arrhythmia. The non-invasive diagnostic tests that
are available generally identify only a small subset of patients who are at
risk of sudden cardiac death or are not sufficiently accurate to warrant
further invasive study or treatment. For example, (i) the identification of
short episodes of non-sustained ventricular tachycardia on a 24-hour Holter
ECG recording, (ii) the presence of late potentials (delayed electrical
activity in the ventricles) on the signal averaged ECG, (iii) reduced beat-to-
beat variability in heart rate, (iv) reduced response in heart rate to blood
pressure changes (baroreceptor sensitivity) and (v) increased variation in the
duration of the QT interval among different electrocardiogram leads in the
same patient, all have been reported to be associated with an increased risk
of sudden cardiac death. However, none of these methods are generally
considered to be sufficiently accurate to warrant further invasive study or
treatment. Finally, ejection fraction, which uses ultrasound or nuclear
imaging to measure the percentage of blood ejected from the heart on each
beat, can indicate a damaged heart which is ineffective in pumping blood. This
is associated with increased rates of sudden cardiac death and with increased
risk of mortality in general; however, because ejection fraction is not
specific in identifying those with high risk of ventricular arrhythmia, it is
not generally considered sufficient to identify those who need to be
invasively studied or treated to prevent sudden death.
 
 NEED FOR IMPROVED DIAGNOSTIC TECHNIQUES
 
  In 1996, developing low-cost, non-invasive technologies to address the
following diagnostic challenges are key problems in cardiac diagnosis:
 
  Sudden Cardiac Death. A study released in April 1996 (the "MADIT Study")
indicates that the prophylactic implantation of ICDs can reduce mortality in
high-risk patients. Although such preventive therapies for sudden cardiac
death have recently become available, non-invasive diagnostic techniques have
not matched these advances. Existing non-invasive diagnostic procedures
generally identify only a small subset of patients who are at risk of sudden
cardiac death or are not sufficiently accurate to warrant further invasive
study or treatment. EP studies are not an attractive alternative
 
                                      24
<PAGE>
 
because they are both invasive and expensive. As a result, despite the fact
that there are approximately 250,000 sudden deaths per year, and at least
several times that number of patients are at risk, fewer than 30,000 received
definitive treatment in 1995. This attests to the need for an accurate, non-
invasive, diagnostic procedure to identify patients at risk of sudden cardiac
death.
 
  Accurate and Cost Effective Detection of Coronary Artery Disease. Despite the
fact that approximately six million standard stress tests are performed each
year in the United States at a cost of approximately $1.8 billion, these tests
are generally not considered to be very accurate in detecting or localizing
coronary artery blockages. Other tests, such as echocardiograms and nuclear
stress tests, are somewhat more accurate but are significantly more expensive.
Coronary angiography, like EP studies, is both invasive and expensive. The need
therefore exists for a more accurate and low cost non-invasive method to
identify patients with ischemic heart disease, particularly in the asymptomatic
population.
 
  Accurate and Timely Diagnosis of Acute Myocardial Infarction. With eight
million patients in the United States arriving at hospital emergency rooms each
year complaining of acute chest pain or other symptoms typical of acute
myocardial infarction, the Company believes that a fast and accurate means of
diagnosing acute myocardial infarction is needed. Existing technologies, such
as the 12 lead ECG, can be inaccurate in the diagnosis of impending myocardial
infarction, and diagnosis based on serial enzyme tests can take too long. With
the recognition that the early use of thrombolytics (blood clot dissolving
drugs) in those with acute myocardial infarction can improve a patient's
outcome, a faster and more accurate method of diagnosis has become increasingly
important.
 
THE CAMBRIDGE HEART SOLUTION
 
  Cambridge Heart has developed an innovative, proprietary non-invasive cardiac
diagnostic system which the Company believes will address shortcomings in
currently available cardiac diagnostic procedures. The Company's initial
product, the CH 2000 System, is designed to perform a broad range of cardiac
stress tests as well as to incorporate the Company's T-wave alternans
technology. Current clinical research into T-wave alternans has demonstrated an
association between T-wave alternans and vulnerability to ventricular
arrhythmia.
 
  The Company's research on its CH 2000 System, using T-wave alternans
technology and Hi-Res electrodes to diagnose ventricular arrhythmias, indicates
that the Company's system has the following potential advantages:
 
  . ACCURACY             Clinical studies to date indicate that the detection
                         of T-wave alternans can identify vulnerability to
                         ventricular arrhythmias with an accuracy superior to
                         that of other non-invasive tests and equal to that of
                         EP studies.
 
  . NON-INVASIVE         Unlike EP studies which require the insertion of
                         electrical catheters into the patient's heart and the
                         administration of local anesthesia, the CH 2000
                         System requires only the placement of electrodes on
                         the patient's chest.
 
  . BROAD APPLICABILITY  Six million standard stress tests and three million
                         imaging stress tests were performed in the United
                         States in 1995. The CH 2000 System, incorporating the
                         Company's proprietary T-wave alternans technology, is
                         designed to simultaneously detect coronary artery
                         disease and assess the risk of sudden cardiac death
                         due to ventricular arrhythmias and with only a modest
                         increase--less than $100--in the total cost of the
                         procedure.
 
  . NON-HOSPITAL SETTING Unlike EP studies and other tests which require a
                         hospital setting, the CH 2000 System can be used in a
                         physician's office.
 
                                       25
<PAGE>
 
  . PROCEDURE COST ADVANTAGES
                         The Company anticipates that a stress test with the
                         CH 2000 System utilizing T-wave alternans technology
                         will cost approximately $400 per procedure, compared
                         with approximately $3,000 to $4,000 for an EP study.
 
  . SYSTEM AFFORDABILITY Starting at under $30,000, the CH 2000 System is only
                         moderately more expensive than standard stress test
                         systems and only 10% to 30% the cost of certain other
                         equipment, such as ultrasound or nuclear imaging
                         equipment.
 
  The Company is also conducting research into the detection of ischemic heart
disease using its cardiac electrical imaging technology. CEI provides an image
of the electrical activity of the heart that is highly sensitive to changes
resulting from ischemia, the lack of oxygen caused by coronary artery disease
or acute myocardial infarction. The Company intends to pursue application of
this technology (i) to provide for enhanced detection and localization of
coronary artery disease during a standard exercise stress test and (ii) to
provide faster and more accurate diagnosis of acute myocardial infarction in
patients who arrive at hospital emergency rooms with acute chest pain.
 
BUSINESS STRATEGY
 
  The Company's principal objective is to establish the CH 2000 System as the
preferred method for the diagnosis of ventricular arrhythmia. The Company also
intends to develop additional cardiac diagnostic products based upon its
proprietary technology. The Company intends to seek FDA clearance or approval
for promotion of the CH 2000 System for the diagnosis of ventricular
arrhythmias and to implement the following strategies:
 
  . Establish Acceptance of the CH 2000 System By Opinion Leaders. The
    Company has enlisted leading medical centers with recognized cardiac care
    expertise in the United States and Europe as the initial users of the CH
    2000 System, and believes that the successful adoption of its products by
    widely recognized cardiology opinion leaders is a critical element in
    fostering the market acceptance of its products. The Company intends to
    continue to work with leading medical centers and to invest in clinical
    studies to establish the efficacy of its products and their
    appropriateness for use in the diagnosis of heart disease.
 
  . Expand Usage to Broad Patient Populations. The Company initially intends
    to target its T-wave alternans technology for the use by
    electrophysiologists on the highest risk patients. The Company will then
    work to expand the adoption of this technology by hospital stress test
    laboratories and for use on intermediate risk patients such as survivors
    of myocardial infarction. Ultimately, the Company intends to market the
    CH 2000 System to office cardiologists for general diagnostic and
    screening applications.
 
  . Utilize the CH 2000 System to Support Additional Diagnostic
    Functions. The Company is conducting research and development of its
    proprietary CEI technology for the diagnosis of coronary artery disease
    and the detection of acute myocardial infarction. The Company is
    evaluating the incorporation of this technology into the CH 2000 System,
    as well as for stand-alone use in hospital emergency rooms.
 
  . Establish Disposable Electrodes Business. The effective implementation of
    the Company's T-wave alternans and CEI technologies require the use of
    proprietary disposable electrodes which the Company believes will provide
    a recurring source of revenue as its installed base of CH 2000 Systems
    expands. The Company intends to continue to invest in its proprietary Hi-
    Res electrodes and other proprietary disposable technologies.
 
 
                                      26
<PAGE>
 
  . Establish Strategic Alliances and Distribution Arrangements. In addition
    to the Company's existing distribution arrangements with Fukuda Denshi
    and Kontron, the Company intends to pursue other strategic relationships,
    as appropriate, in order to broaden the acceptance of its products as
    quickly as possible and to increase the use of its disposable electrodes.
 
  . Protect and Enhance Proprietary Technology Base. The Company believes
    that its intellectual property and technological expertise are important
    competitive resources. The Company continues to evaluate markets and
    products to exploit its underlying technology. In addition, the Company
    maintains a program of intellectual property protection, both to assure
    that the proprietary technology developed by the Company is appropriately
    protected, and, where necessary, to assure that there is no infringement
    of the Company's proprietary technologies by competitive technologies.
 
PRODUCTS AND APPLICATIONS
 
  The CH 2000 System is designed to perform conventional cardiac stress tests
as well as to incorporate the Company's proprietary T-wave alternans
technology. Current clinical research into T-wave alternans has demonstrated
an association between certain T-wave alternans and vulnerability to
ventricular arrhythmias. The Company's proprietary T-wave alternans technology
permits evaluation, computation and recording of T-wave alternans during
bicycle exercise, atrial pacing or pharmacological stress. Because of the need
to record very small variations in electric signals for precise T-wave
alternans measurement, the CH 2000 System incorporates proprietary Hi-Res
electrodes and proprietary signal processing algorithms to minimize noise
levels resulting from patient movement.
 
 THE CH 2000 SYSTEM
 
  The Company's CH 2000 System is a fully-featured diagnostic system that
includes a cart- mounted computer with proprietary software, integral ECG
system, display, keyboard and output devices which can be configured for both
hospital and office settings. This system is designed to support a broad range
of standard and physician-customized protocols for the conduct and measurement
of cardiac stress tests and is compatible with both standard electrodes and
with the Company's Hi-Res electrodes for T-wave alternans analysis. The CH
2000 System is capable of controlling both treadmill and bicycle ergometers
and is well suited for standard, nuclear or echocardiogram stress tests.
 
  In addition to the incorporation of T-wave alternans technology, the CH 2000
System has been designed to provide a broad range of special features,
including the following:
 
  . A 15-inch high-resolution color monitor for the display of critical data
    and parameters, including the display of full 12-lead output, or that of
    any specific lead, as required.
 
  . The capacity to generate printed output including 12-lead reports, a
    summary of an entire stress test on one page, and alternans levels versus
    normal heart rate for an entire study.
 
  . The incorporation of hard disk and optional optical disk storage of data
    acquired during the stress test, facilitating both post-test analysis and
    post-test annotation of results.
 
  . A modular design using standard computer components for easy maintenance
    and upgrade.
 
  Although the Company's strategic focus is on its proprietary T-wave
alternans and CEI technologies, the base CH 2000 System without such
technologies is viewed by Kontron and Fukuda Denshi, the Company's
international distribution partners, as being a highly competitive stress test
system, and the Company expects these distributors to position the system as
their top-end offering in the stress test market.

 ASSOCIATION OF T-WAVE ALTERNANS AND VENTRICULAR ARRHYTHMIAS
 
 
  The association between ventricular arrythmia and extremely low levels of T-
wave alternans (not detectable by visual inspection of the ECG) was unknown
until recently. Research conducted in Dr. Richard Cohen's laboratory at MIT
beginning in the early 1980's indicated that analysis of microvolt (millionth
of a volt) levels of T-wave alternans was predictive of vulnerability to
ventricular arrhythmias responsible for sudden cardiac death. Dr. Cohen and
his associates developed the technology to quantify this electrical conduction
pattern which has been exclusively licensed to the Company and which forms the
basis of the Company's proprietary technology.
 
  In a collaborative study of 83 patients conducted at Massachusetts General
Hospital ("MGH") in collaboration with Dr. Cohen's laboratory at MIT, which
was published in the New England Journal of Medicine in December 1994, the
detection of T-wave alternans at certain levels in patients referred for EP
studies was shown to be as accurate as invasive EP testing in predicting
sudden cardiac death and life-threatening ventricular arrhythmias. In the high
risk population studied for up to 20 months following the procedure, an
actuarial analysis involving 66 patients indicated that 81% of those testing
positive for T-wave alternans died or suffered a life-threatening arrhythmia
within 20 months of the test; only 6% of the patients testing negative for T-
wave alternans did so. As indicated by the chart below, these results were
equivalent to those obtained with invasive EP testing and were far superior to
those which have been reported using other non-invasive methods.
 
 
         [Graph: T-wave alternans compared to EP testing appears here]

 
                                       28

  The Company has sponsored and is continuing to sponsor a number of clinical
studies relating to the CH 2000 System, its T-wave alternans technology and
its Hi-Res electrodes to establish the prognostic value of T-wave alternans
technology. There can be no assurance that the results of such studies will
confirm earlier studies, or that regulatory clearance will be received. The
following table sets forth clinical studies concerning T-wave alternans:

 CARDIAC ELECTRICAL IMAGING FOR ISCHEMIC HEART DISEASE
 
  The Company is conducting research into systems to detect ischemic heart
disease based upon its CEI technology, which provides an image of the
electrical activity of the heart. Animal studies and an initial human study
indicate that CEI is highly sensitive to changes resulting from ischemia, the
lack of oxygen caused by coronary artery disease or acute myocardial
infarction. The Company intends to pursue application of this technology (i)
to provide for enhanced detection and localization of coronary artery disease
during a standard exercise stress test and (ii) to provide faster and more
accurate diagnosis of acute myocardial infarction in patients who arrive at
hospital emergency rooms with acute chest pain.
 
  Cardiac electrical imaging utilizes the Company's own signal processing
software and a proprietary array of disposable "Laplacian" electrodes. Each
electrode is focused in that it provides signals from a highly localized
region of the heart, in contrast to standard electrodes which record signals
from all regions of the heart. An array of Laplacian electrodes provides a
highly sensitive means of detecting the presence of ischemia and localizing
the regions of ischemia within the heart.
 
  The Company is evaluating the incorporation of CEI technology into the CH
2000 System, and intends to initiate additional clinical studies of this
technology in the second half of 1996. In addition, the Company is evaluating
the commercial feasibility of a portable system incorporating CEI technology
for hospital emergency room use to detect acute myocardial infarction.
 
MARKETING AND SALES
 
  The Company is targeting the market for cardiac stress systems with its CH
2000 System. In 1995, approximately 3,000 cardiac stress systems were sold in
the United States, and the Company believes that the total installed U.S. base
of cardiac stress systems is approximately 23,000 units.
 
  The Company believes that the key to the adoption of the CH 2000 System and
market acceptance of its proprietary technologies to diagnose heart disease
will be continued clinical development and positive clinical experience with
the CH 2000 System, together with the publication of these results in medical
journals. The commercial success of the CH 2000 System will require marketing,
educational and sales efforts to encourage cardiologists and other medical
professionals to utilize T-wave alternans testing and, eventually, CEI, in
their medical practices. The Company plans to establish centers of excellence
at leading cardiology medical centers, fund studies to further demonstrate the
efficiency of its technologies, support seminars and symposiums and
participate in industry trade shows and academic conferences.
 
  The Company intends to market its products in the United States primarily
through a direct sales force in major urban areas and through independent
distributors elsewhere. The Company has hired a Vice President of Sales and
Business Development to lead its sales and marketing organization and is in
the process of hiring additional sales and support personnel as it introduces
the CH 2000 System in the U.S. market.
 
  The Company intends to market its products internationally through
independent distributors. The Company has entered into distribution agreements
with Kontron for the sale of the CH 2000 System in Europe and the Middle East,
and with Fukuda Denshi for the sale of the CH 2000 System in Japan. The
Company sold a limited number of demonstration units to Fukuda Denshi in 1995.
The Company began commercial shipment of complete CH 2000 Systems, including
Hi-Res electrodes, to Kontron in April 1996, and commercial shipments to
Fukuda Denshi are expected to begin following the approval of the Japanese
Ministry of Health, anticipated in late 1996.
 
MANUFACTURING
 
  Cambridge Heart performs final assembly, including hardware and software
components, and testing of its products, at its headquarters in Bedford,
Massachusetts. The Company believes its facility will be adequate to meet its
needs through 1997. The Company will be required to meet and adhere
 
                                      30
<PAGE>
 
to all applicable requirements of U.S. and international regulatory agencies,
including GMP standards. The Company's manufacturing facilities are subject to
periodic inspection by both U.S. and international regulatory agencies. See
"--Government Regulation".
 
  The manufacturing process consists primarily of final assembly of purchased
components, testing operations and packaging. Components are purchased
according to the Company's specifications and are inspected and tested by the
Company. The Company relies on outside vendors to manufacture certain major
components used in the CH 2000 System, including its Hi-Res electrodes. A
number of components are currently supplied by sole source vendors. See "Risk
Factors--Dependence Upon Key Suppliers".
 
RESEARCH AND DEVELOPMENT
 
  The Company has licensed four different product technologies from MIT,
including the technology underlying T-wave alternans and CEI, which were
developed at MIT over a period of approximately ten years at a cost of over
five million dollars. The Company also has rights to any follow-on
technologies developed at MIT which are derived from the four original
technologies. The Company is actively engaged in commercializing the CH 2000
System, and is conducting research and development with respect to its CEI
technology, which is investigational. The Company is evaluating this
technology both for incorporation into the CH 2000 System and for stand-alone
use in hospital emergency rooms.
 
  The Company believes that its technology base will permit it to develop
additional products for use in the diagnosis and treatment of cardiac disease.
Other cardiac diagnostic and treatment areas the Company intends to
investigate include monitoring of blood flow from the heart as a method of
measuring hemodynamic deterioration and the measurement of beat-to-beat
fluctuation in heart rate, blood pressure and respiration rate to measure and
quantify directly the functioning of the body's regulatory mechanisms. These
technologies will require significant additional research and development
expenditures by the Company in the event it should elect to pursue any of
these technologies and the Company has not yet commenced any product
development or clinical testing of these technologies.
 
  The Company's research and development expenses were $589,000 in 1993,
$1,124,000 in 1994 and $1,560,000 in 1995. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations". The Company
expects research and development expenses to increase significantly in the
future as it develops additional products and funds clinical trials on its
products. As of May 1, 1996 the Company had ten employees engaged in research
and development activities.
 
PATENTS, TRADE SECRETS AND PROPRIETARY RIGHTS
 
  The computer algorithms that allow the CH 2000 System to measure T-wave
alternans and certain aspects of the Company's CEI technology, including the
CEI electrodes, are covered by U.S. patents issued to MIT that are licensed
exclusively to the Company. The Company has applied for a U.S. patent covering
the use of exercise or physiological stress in the measurement of T-wave
alternans, which has been allowed, and corresponding foreign patents are
pending. The Company has also applied for U.S. and foreign patents covering
additional proprietary signal processing algorithms and its Hi-Res electrodes
for use in the measurement of T-wave alternans. The Company owns or is the
exclusive licensee of seven patents issued or allowed and six patents pending
in the United States, with 17 corresponding foreign patents issued or pending
with respect to its technololgy.
 
  The Company believes that its intellectual property and expertise, as
originally licensed from MIT and thereafter developed at the Company,
constitute an important competitive resource, and the Company intends to
continue to aggressively evaluate markets and products which are most
appropriate to exploit the expertise licensed by, and developed at, the
Company. In addition, the
 
                                      31
<PAGE>
 
Company intends to maintain an active program of intellectual property
protection, both to assure that the proprietary technology developed by the
Company is appropriately protected, and, where necessary, to assure that there
is no infringement of the Company's proprietary technology by competitive
technologies.
 
  The Company's future success will depend, in part, on its ability to
continue to develop patentable products, enforce its patents and obtain patent
protection for its products both in the United States and in other countries.
However, the patent positions of medical device companies, including the
Company, are generally uncertain and involve complex legal and factual
questions. No assurance can be given that patents will issue from any patent
applications owned by or licensed to the Company or that, if patents do issue,
the claims allowed will be sufficiently broad to protect the Company's
technology. In addition, no assurance can be given that any issued patents
owned by or licensed to the Company will not be challenged, invalidated or
circumvented, or that the rights granted thereunder will provide competitive
advantages to the Company.
 
  The commercial success of the Company will also depend in part on its
neither infringing patents issued to others nor breaching the licenses upon
which the Company's products are based. The Company has licensed significant
technology and patents from third parties, including patents and technology
relating to T-wave alternans and CEI licensed from MIT. The Company's licenses
of patents and patent applications impose various commercialization,
sublicensing, insurance, royalty and other obligations on the Company. Failure
of the Company to comply with these requirements could result in conversion of
the licenses from being exclusive to nonexclusive in nature or, in some cases,
termination of the license.
 
  The MIT License Agreements provide that the licenses granted therein (the
"MIT Licenses") are exclusive worldwide for a period ending on the earlier to
occur of either 12 years after the first commercial sale of products employing
licensed technology or the expiration of 15 years after the effective date of
the Agreements. MIT reserves the right to practice under the licensed patent
rights and to use and distribute to third parties for noncommercial research
purposes the underlying technology . The MIT License Agreements provide that
the Company must achieve certain milestones, which include raising equity
capital, filing applications with the FDA and generating specified revenues
beginning in 1998. If such milestones are not achieved, MIT has the right to
terminate the MIT Licenses. The MIT License Agreements also set forth certain
royalties to be paid by the Company to MIT and contain provisions relating to
potential infringement of the patent rights that allow, but do not require,
either party to take action against such infringement. The MIT License
Agreements further provide that the Company will indemnify MIT for all losses
suffered by MIT through the Company's use of the licensed technology. The
royalty rate under each of the licenses is 2%, but has been amended in the
case of the T-wave alternans technology to 1.5% due to the significant value
added by the Company. For a description of the Company's license agreement
with Dr. Cohen, see "Certain Transactions".
 
  The Company also relies on unpatented trade secrets to protect its
proprietary technology, and no assurance can be given that others will not
independently develop or otherwise acquire substantially equivalent
technologies or otherwise gain access to the Company's proprietary technology
or disclose such technology or that the Company can ultimately protect
meaningful rights to such unpatented proprietary technology. The Company
relies on confidentiality agreements with its collaborators, employees,
advisors, vendors and consultants to protect its trade secrets. There can be
no assurance that these agreements will not be breached, that the Company
would have adequate remedies for any breach or that the Company's trade
secrets will not otherwise become known or be independently developed by
competitors. Failure to obtain or maintain patent and trade secret protection
for the Company's products, for any reason, would have a material adverse
effect on the Company's business, financial condition and results of
operations.

COMPETITION
 
  The medical device market is characterized by intensive development efforts
and rapidly advancing technology. The future success of the Company will
depend, in large part, upon its ability to anticipate and keep pace with
advancing technology and competitive innovations. However, there can be no
assurance that the Company will be successful in identifying, developing and
marketing new products or enhancing its existing products. In addition, there
can be no assurance that new products or alternative diagnostic techniques
will not be developed that will render the Company's current or planned
products obsolete or inferior. Rapid technological development by competitors
may result in the Company's products becoming obsolete before the Company
recovers a significant portion of the research, development and
commercialization expenses incurred with respect to such products. Alternative
technologies exist today in each of the areas being addressed by the Company,
including ECGs, Holter monitors, ultrasound tests and systems for measuring
cardiac late potentials.
 
  Competition from medical devices which help to diagnose cardiac disease is
intense and likely to increase. The Company's competitors include
manufacturers of ECG stress test equipment, including major multinational
companies. Many of the Company's competitors and potential competitors have
substantially greater capital resources, name recognition, research and
development experience and regulatory, manufacturing and marketing
capabilities. Many of these competitors offer well established, broad product
lines and ancillary services not offered by the Company. Some of the Company's
competitors have long-term or preferential supply arrangements with hospitals
that may act as a barrier to market entry. Other large health care companies
may enter the non-invasive cardiac diagnostic product market in the future.
Competing companies may succeed in developing products that are more
efficacious or less costly than any that may be developed by the Company, and
such companies also may be more successful than the Company in producing and
marketing such products or their existing products. Competing companies may
also introduce competitive pricing pressures that may adversely affect the
Company's sales levels and margins. There can be no assurance that the Company
will be able to compete successfully with existing or new competitors.
 
GOVERNMENT REGULATION
 
  The manufacture and sale of medical devices intended for commercial
distribution are subject to extensive governmental regulation in the United
States. Medical devices are regulated in the United States by the FDA and
generally require pre-market clearance or pre-market approval prior to
commercial distribution. In addition, certain material changes or
modifications to medical devices also are subject to FDA review and clearance
or approval. The FDA regulates the research, testing, manufacture, safety,
labeling, storage, record keeping, advertising and distribution of medical
devices in the United States. Noncompliance with applicable requirements can
result in failure of the government to grant pre-market clearance or approval
for devices, withdrawal of approval, total or partial suspension of
production, fines, injunctions, civil penalties, recall or seizure of
products, and criminal prosecution.
 
  Medical devices are classified into one of three classes, Class I, II or
III, on the basis of the controls deemed by the FDA to be necessary to
reasonably ensure their safety and effectiveness.
 
  Class I devices are subject to general controls (e.g., labeling, pre-market
notification and adherence to GMP standards). Class II devices are subject to
general controls and special controls (e.g., performance standards, post-
market surveillance, patient registries and FDA guidelines). Generally, Class
III devices are those that must receive pre-market approval by the FDA to
ensure their safety and effectiveness (e.g., life-sustaining, life-supporting
and implantable or new devices which have not been found to be substantially
equivalent to legally marketed devices), and require clinical testing to
ensure safety and effectiveness and FDA approval prior to marketing and
distribution. The FDA also has the authority to require clinical testing of
Class I and Class II devices. A PMA application must be filed if a proposed
device is not substantially equivalent to a legally marketed predicate device
or if it is a Class III device for which the FDA has called for such
application.
 
                                      33
<PAGE>
 
  Generally, before a new device can be introduced into the market in the
United States, the manufacturer or distributor must obtain FDA clearance of a
pre-market notification ("510(k) notification") submission or approval of a
PMA application. If a medical device manufacturer or distributor can establish
that a device is "substantially equivalent" to a legally marketed Class I or
Class II device, or to a Class III device for which the FDA has not called for
PMAs, the manufacturer or distributor may seek clearance from the FDA to
market the device by filing a 510(k) notification. The 510(k) notification may
need to be supported by appropriate data establishing the claim of substantial
equivalence to the FDA. The FDA recently has been requiring a more rigorous
demonstration of substantial equivalence.
 
  Following submission of the 510(k) notification, the manufacturer or
distributor may not place the device into commercial distribution until an
order is issued by the FDA. At this time, the FDA typically responds to the
submission of a 510(k) notification within 90 to 200 days. An FDA order may
declare that the device is substantially equivalent to a legally marketed
device and allow the proposed device to be marketed in the United States. The
FDA, however, may determine that the proposed device is not substantially
equivalent or requires further information, including clinical data, to make a
determination regarding substantial equivalence. Such determination or request
for additional information could delay market introduction of the product that
is the subject of the 510(k) notification.
 
  If human clinical trials of a device are required and if the device presents
a "significant risk," the manufacturer or distributor of the device is
required to file an investigational device exemption ("IDE") application with
the FDA prior to commencing human clinical trials. The IDE application must be
supported by data, typically the result of animal and, possibly, mechanical
testing. If the IDE application is approved by the FDA, human clinical trials
may begin at a specific number of investigational sites with a maximum number
of patients, as approved by the FDA.
 
  If a manufacturer or distributor of medical devices cannot establish that a
proposed device is substantially equivalent to a legally marketed device, the
manufacturer or distributor must seek pre-market approval of the proposed
device through submission of a PMA application. A PMA application must be
supported by extensive data, including preclinical and clinical trial data, as
well as extensive literature to prove the safety and effectiveness of the
device. Following receipt of a PMA application, if the FDA determines that the
application is sufficiently complete to permit a substantive review, the
agency will "file" the application. The FDA has 180 days to review a PMA
application, although the review of an application more often occurs over a
protracted time period, and generally takes two years or more from the filing
date to complete.
 
  The PMA approval process can be expensive, uncertain and lengthy. A number
of devices for which pre-market approval has been sought have never been
approved for marketing. The review time is often significantly extended by the
FDA, which may require more information or clarification of information
already provided in the submission. During the review period, an advisory
committee likely will be convened by the FDA to review and evaluate the
application and provide recommendations to the agency as to whether the device
should be approved. In addition, the FDA will inspect the manufacturing
facility to ensure compliance with the GMP regulations for medical devices
prior to approval of the PMA application. If granted, the approval may include
significant limitations on the indicated uses for which a product may be
marketed.
 
  Any products manufactured or distributed by the Company are subject to
pervasive and continuing regulation by the FDA including record keeping
requirements, reporting of adverse experience with the use of the device,
post-market surveillance, post-market registry and other actions deemed
necessary by the FDA. The FDA's regulations require agency approval of a PMA
or 510(k) supplement for certain changes if they affect the safety and
effectiveness of the device, including, but not limited to, new indications
for use, labeling changes, the use of a different facility to manufacture,
process or package the device, changes in manufacturing methods or quality
control systems and changes in performance
 
                                      34
<PAGE>
 
or design specifications. Failure by the Company to receive approval of a PMA
or 510(k) supplement regarding the use of a different manufacturing facility
or any other change affecting the safety or effectiveness of an approved or
cleared device on a timely basis, or at all, would have a material adverse
effect on the Company's business, financial condition and results of
operations.
 
  Sales of medical device products outside the United States are subject to
foreign regulatory requirements that vary from country to country. The time
required to obtain approvals required by foreign countries may be longer or
shorter than that required for FDA approval, and requirements for licensing
may differ from FDA requirements. Failure to comply with regulatory
requirements could have a material adverse effect on the Company's business,
financial condition and results of operations. The current regulatory
environment in Europe for medical devices differs significantly from that in
the United States. There is currently no universally accepted definition of a
medical device in Europe and there is no common approach to medical device
regulation among the various countries. There are several different regulatory
regimes operating within the different European countries. Regulatory
requirements for medical devices range from no regulations in some countries
to rigorous regulations approaching the requirements of the FDA's regulations
for Class III medical devices. Several countries require that device safety be
demonstrated prior to approval for commercialization. The regulatory
environment in certain European countries is expected to undergo major changes
as a result of the creation of medical directives by the European Union.
 
  The CH 2000 System has received 510(k) clearance from the FDA for sale in
the United States. A 510(k) pre-market approval application for the Hi-Res
electrodes was filed in May 1996 and clearance is expected to be received in
the fourth quarter of 1996. The timing of the electrode clearance cannot be
predicted with great accuracy. However, because no claims concerning T-wave
alternans are being made for the electrodes (the only claim is that they
reduce noise in the ECG which is readily demonstrable), and because the
Company believes the electrodes meet all applicable safety and performance
standards, it is anticipated that the electrodes will be cleared under the
510(k) process. Until the electrodes are cleared, the Company can, however,
market and sell the CH 2000 System without the Hi-Res electrodes as well as
make the electrodes available at cost to those conducting clinical studies of
T-wave alternans. However, the Company has chosen to limit sales of the CH2000
System in the United States to a limited number of clinical sites until the
Hi-Res electrodes receive FDA clearance.
 
  The 510(k) clearance for the CH 2000 System includes the claim that the CH
2000 System can measure T-wave alternans but no claim about the applicability
or prognostic use of the alternans measurement. The Company is currently
conducting further clinical studies and expects to make a subsequent 510(k)
submission to the FDA with additional clinical data in order to obtain a
subsequent clearance with broader claims. This submission is expected to be
made in the first half of 1997, with clearance possible by early 1998, but
there can be no assurance that such clearance will be obtained on a timely
basis, if at all. Until clearance of the broader prognostic claims is
obtained, the Company may not publicize the prognostic capabilities of its T-
wave alternans technology.
 
  Internationally, the Company received the CE mark for sale in Europe for the
CH 2000 System in April 1996, and application has been made for approval with
the Ministry of Health in Japan.
 
REIMBURSEMENT
 
  Suppliers of health care products and services are greatly affected by
Medicare, Medicaid and other government insurance programs, as well as by
private insurance reimbursement programs. Third party payors (Medicare,
Medicaid, private health insurance, health administration authorities in
foreign countries and other organizations) may affect the pricing or relative
attractiveness of the Company's products by regulating the maximum amount of
reimbursement provided for by such payors to the physicians and clinics
utilizing the CH 2000 System or by taking the position that such reimbursement
is not available at all.
 
                                      35
<PAGE>
 
  The Company believes that the availability and level of third party
reimbursement will influence the decisions of physicians, clinics and
hospitals to purchase and use the Company's products and thereby affect the
pricing of the Company's products. The Company's strategy to obtain approval
of payments to physicians using its products includes (i) enlisting the
assistance of leading cardiac specialists in making presentations to health
care administrators to inform them of the benefits of the additional data
provided by the CH 2000 System, and of the potential pharmacoeconomic benefits
resulting from the use of the products and (ii) working with professional
organizations to foster awareness and support for its products.
  Several states and the federal government are investigating a variety of
alternatives to reform the health care delivery system and reduce and control
health care spending. These reform efforts include proposals to limit spending
on health care items and services, limit coverage for new technology and limit
or control directly the price health care providers and drug and device
manufacturers may charge for their services and products. The scope and timing
of such reforms cannot be predicted, but if adopted and implemented, such
reforms could have a material adverse effect on the Company. See "Risk
Factors--Uncertainty Relating to Third-Party Reimbursement".

(1) The expiration date of each option is the tenth anniversary of the date on
    which it was originally granted. These options are intended to qualify as
    incentive stock options and are exercisable in five equal installments
    commencing on the first anniversary of the date of grant.
(2) The amounts shown on this table represent hypothetical gains that could be
    achieved for the respective options if exercised at the end of the option
    term. These gains are based on assumed rates of stock appreciation of 5%
    and 10%, compounded annually from the date the respective options were
    granted to their expiration date. The gains shown are net of the option
    exercise price, but do not include deductions for taxes or other expenses
    associated with the exercise. Actual gains, if any, on stock option
    exercises will depend on the future performance of the Common Stock, the
    option holders' continued employment through the option period, and the
    date on which the options are exercised.

Furthermore, Mr. Arnold is entitled to terminate his employment agreement
within 90 days of a Change in Control of the Company and to receive severance
compensation equal to nine months' base salary. The agreement also contains a
non-competition covenant pursuant to which Mr. Arnold is prohibited from

EMPLOYEE BENEFIT PLANS
 
 1993 AMENDED AND RESTATED INCENTIVE AND NON-QUALIFIED STOCK OPTION PLAN
 
  The Company's 1993 Incentive and Non-Qualified Stock Option Plan (the "1993
Option Plan") was adopted by the Company in September 1993. The 1993 Option
Plan provides for the grant of
 
                                      42
<PAGE>
 
stock options to key employees and consultants of the Company and any parent
or subsidiary of the Company. Under the 1993 Option Plan, the Company may
grant options that are intended to qualify as incentive stock options within
the meaning of Section 422 of the Internal Revenue Code of 1986, as amended
(the "Code") ("incentive stock options"), or options not intended to qualify
as incentive stock options ("non-statutory options"). Incentive stock options
may be granted only to employees of the Company. A total of 1,688,663 shares
of Common Stock may be issued upon the exercise of options granted under the
1993 Option Plan.
 
  The 1993 Option Plan is administered by the Stock Option Committee of the
Board of Directors. Subject to the provisions of the 1993 Option Plan, the
Stock Option Committee has the authority to select the employees to whom
options are granted and determine the terms of each option, including (i) the
number of shares of Common Stock subject to the option, (ii) when the option
becomes exercisable, (iii) the option exercise price, which, in the case of
incentive stock options, must be at least 100% (110% in the case of incentive
stock options granted to a stockholder owning in excess of 10% of the
Company's Common Stock) of the fair market value of the Common Stock as of the
date of grant, and (iv) the duration of the option (which, in the case of
incentive stock options, may not exceed ten years (five years in the case of a
stockholder owning in excess of 10% of the Company's Common Stock).
 
  Payment of the option exercise price may be made in cash, by check or, in
some circumstances, by delivery of shares of Common Stock, provided such
shares have been held for at least six months. The 1993 Option Plan provides
further that the Stock Option Committee may allow additional forms of payment,
so long as such forms of payment are consistent with applicable laws and
regulations. Options are not assignable or transferable except by will or the
laws of descent and distribution and, in the case of non-statutory options,
pursuant to a qualified domestic relations order (as defined in the Code).
 
  As of May 1, 1996, the Company had 18 full-time employees, all of whom were
eligible to participate in the 1993 Option Plan; however, the Company does not
intend to award options under the 1993 Option Plan after the closing of the
Offering.
 
  The 1993 Stock Option Plan places certain restrictions on the transfer of
stock acquired upon the exercise of incentive stock options granted under the
1993 Option Plan. The Stock Option Committee may, in its sole discretion,
include additional provisions in any option or award granted or made under the
1993 Option Plan, including without limitation restrictions on transfer,
repurchase rights, commitments to pay cash bonuses, to make, arrange for or
guaranty loans or to transfer other property to optionees upon exercise of
options, or such other provisions as shall be determined by the Stock Option
Committee, so long as not inconsistent with the 1993 Option Plan or with
applicable law. The Stock Option Committee may also, in its sole discretion,
accelerate or extend the date or dates on which all or any particular option
or options granted under the 1993 Option Plan may be exercised.
 
 1996 EQUITY INCENTIVE PLAN
 
  The Company's 1996 Equity Incentive Plan (the "1996 Plan") was adopted by
the Board of Directors on May 29, 1996 and approved by the stockholders of the
Company on June  , 1996. The 1996 Plan provides for the grant of stock awards,
restricted stock awards, stock options, stock appreciation rights and
performance shares, to employees, officers and directors of, and consultants
or advisers to, the Company and its subsidiaries. Under the 1996 Plan, the
Company may grant incentive stock options or nonstatutory options. Incentive
stock options may only be granted to employees of the Company. A total of
1,000,000 shares of Common Stock may be granted under the 1996 Plan. Unless
otherwise terminated, the 1996 Plan will terminate on June  , 2006.
 
  The 1996 Plan is administered by the Compensation Committee of the Board of
Directors. Subject to the provisions of the 1996 Plan, the Compensation
Committee has the authority to select the employees to whom options are
granted and determine the terms of each option, including (i) the
 
                                      43
<PAGE>
 
number of shares of Common Stock subject to the option, (ii) when the option
becomes exercisable, (iii) the option exercise price, which, in the case of
incentive stock options, must be at least 100% (110% in the case of incentive
stock options granted to a stockholder owning in excess of 10% of the
Company's Common Stock) of the fair market value of the Common Stock as of the
date of grant, and (iv) the duration of the option (which, in the case of
incentive stock options, may not exceed ten years; five years in the case of
incentive stock options granted to stockholders owning in excess of 10% of the
Company's Common Stock). The Compensation Committee may, in its sole
discretion, include additional provisions in any option or award granted or
made under the 1996 Plan, so long as not inconsistent with the 1996 Plan or
applicable law. The Compensation Committee may also, in its sole discretion,
accelerate or extend the date or dates on which all or any particular option
or options granted under the 1996 Plan may be exercised.
 
  Payment of the option exercise price may be made in cash, shares of Common
Stock, a combination of cash or stock, by a broker-assisted cashless exercise
or by any other method (including delivery of a promissory note payable on
terms specified by the Compensation Committee) approved by the Compensation
Committee consistent with Section 422 of the Code and Rule 16b-3 ("Rule 16b-
3") under the Securities Exchange Act of 1934, as amended (the "Exchange
Act").
 
  As of May 15, 1996, the Company had 18 employees, all of whom were eligible
to participate in the 1996 Plan. The maximum number of shares which may be
granted in any calendar year to any optionee is 300,000. The number of
individuals receiving stock options varies from year to year depending upon
various factors, such as the number of promotions and the Company's hiring
needs during the year, and thus the Company cannot now determine the number of
shares of Common Stock to be awarded to any particular current executive
officer, to all current executive officers as a group or to non-executive
employees as a group.
 
  All options are nontransferable other than by will or the law of descent and
distribution and, in the case of options which are not incentive stock
options, pursuant to a qualified domestic relations order. Incentive stock
options are exercisable during the lifetime of the option holder only while
the option holder is in the employ of the Company, or within three months
after termination of employment. In the event that termination is due to death
or disability, or if death occurs within three months after termination, the
option is exercisable for a one-year period thereafter.
 
  To the extent not exercised, all options granted under the 1996 Plan shall
terminate immediately prior to a dissolution or liquidation of the Company. In
the event of a merger of the Company or the sale of substantially all of the
assets of the Company, the Board of Directors shall have the discretion to
accelerate the vesting of the options granted under the 1996 Plan.
 
  Federal Income Tax Consequences. No taxable income will be recognized by an
optionee upon the grant or exercise of an incentive stock option (provided
that the difference between the option exercise price and the fair market
value of the stock on the date of exercise must be included in the optionee's
"alternative minimum taxable income"), and no corresponding expense deduction
will be available to the Company. Generally, if an optionee holds shares
acquired upon the exercise of incentive stock options until the later of (i)
two years from the grant of the option and (ii) one year from the date of
transfer of the purchased shares to him or her (the "Statutory Holding
Period"), any gain to the optionee upon a sale of such shares will be treated
as capital gain. The gain recognized upon the sale of the stock is the
difference between the option price and the sale price of the stock. The net
federal income tax effect on the holder of incentive stock options is to
defer, until the stock is sold, taxation of any increase in the stock's value
from the time of grant to the time of exercise, and to cause such increase to
be treated as capital gain.
 
  If the optionee sells the shares prior to the expiration of the Statutory
Holding Period, he or she will realize taxable income at ordinary income tax
rates in an amount equal to the lesser of (i) the fair market value of the
shares on the date of exercise less the option price, or (ii) the amount
realized on
 
                                      44
<PAGE>
 
the sale less the option price, and the Company will receive a corresponding
business expense deduction. Any additional gain will be treated as long-term
capital gain if the shares are held for more than one year prior to the sale
and as short-term capital gain if the shares are held for a shorter period. If
the optionee sells the stock for less than the option price, he or she will
recognize a capital loss equal to the difference between the sale price and
the option price. The loss will be a long-term capital loss if the shares are
held for more than one year prior to the sale and short-term capital loss if
the shares are held for a shorter period.
 
  No taxable income is recognized by the optionee upon the grant of a
nonstatutory option. The optionee must recognize as ordinary income in the
year in which the option is exercised the amount by which the fair market
value of the purchased shares on the date of exercise exceeds the option price
(and the Company may be required to withhold an appropriate amount for tax
purposes). If the optionee is a person who is required to file reports
pursuant to Section 16(a) of the Exchange Act, then upon the exercise of an
option within six months from the date of grant no income will be recognized
by the optionee until six months have expired from the date the option was
granted, and the income then recognized will include any appreciation in the
value of the shares during the period between the date of exercise and the
date six months after the date of grant (unless the optionee makes an election
under Section 83(b) of the Code to have the difference between the exercise
price and fair market value on the date of exercise recognized as ordinary
income as of the time of exercise). The Company will be entitled to a business
expense deduction equal to the amount of ordinary income recognized by the
optionee, subject to the limitations of Section 162(m) of the Code. Any
additional gain or any loss recognized upon the subsequent disposition of the
purchased shares will be a capital gain or loss, and will be a long-term gain
or loss if the shares are held for more than one year.
 
 1996 EMPLOYEE STOCK PURCHASE PLAN
 
  The Company's 1996 Employee Stock Purchase Plan (the "Purchase Plan") was
adopted by the Board of Directors in May 1996, was approved by the
stockholders in June 1996, and will become effective upon the closing of this
Offering. The Purchase Plan authorizes the issuance of up to a total of
100,000 shares of Common Stock to participating employees.
 
  All employees of the Company, including directors of the Company who are
employees, are eligible to participate in the Purchase Plan. Employees who
would immediately after the grant own 5% or more of the total combined voting
power or value of the stock of the Company or any subsidiary are not eligible
to participate. As of May 1, 1996, 17 of the Company's employees would have
been eligible to participate in the Purchase Plan.
 
  On the first day of a designated payroll deduction period (the "Offering
Period"), the Company will grant to each eligible employee who has elected to
participate in the Purchase Plan an option to purchase shares of Common Stock
as follows: The employee may authorize an amount (a whole percentage from 1%
to 10% of such employee's regular pay) to be deducted by the Company from such
pay during the Offering Period. On the last day of the Offering Period, the
employee is deemed to have exercised the option, at the option exercise price,
to the extent of accumulated payroll deductions. Under the terms of the
Purchase Plan, the option price is an amount equal to 85% of the fair market
value per share of the Common Stock on either the first day or the last day of
the Offering Period, whichever is lower. In no event may an employee purchase
in any one Offering Period a number of shares which is more than 15% of the
employee's annualized base pay divided by 85% of the market value of a share
of Common Stock on the commencement date of the Offering Period. The
Compensation Committee may, in its discretions, choose an Offering Period of
12 months or less for each of the Offerings and choose a different Offering
Period for each Offering.
 
  If an employee is not a participant on the last day of the Offering Period,
such employee is not entitled to exercise any option, and the amount of such
employee's accumulated payroll deductions will be refunded. An employee's
rights under the Purchase Plan terminate upon voluntary withdrawal
 
                                      45
<PAGE>
 
from the Purchase Plan at any time or when such employee ceases employment for
any reason, except that upon termination of employment because of death, the
employee's beneficiary has certain rights to elect to exercise the option to
purchase the shares which the accumulated payroll deductions in the
participant's account would purchase at the date of death.
 
  Federal Income Tax Consequences. The Purchase Plan is intended to be an
"Employee Stock Purchase Plan" within the meaning of Section 423 of the Code
which provides that the participant does not have to pay any federal income
tax upon enrolling in an offering under the Purchase Plan or upon purchasing
shares of the Common Stock at the end of an offering. The participant is,
however, required to pay federal income tax at the time he or she sells such
shares on the excess, if any, of the price at which he or she sells the shares
over the price he or she paid for them.
 
  If the participant has owned the shares for more than one year and disposes
of them at least two years after the day the offering commenced, he will be
taxed as follows. If the sale of the shares is less than the price paid for
the shares under the Purchase Plan, the participant will incur a long-term
capital loss in an amount equal to the excess of the price paid over the sale
price. If the sale price is higher than the price paid under the Purchase
Plan, the participant will have to recognize ordinary income in an amount
equal to the lesser of (a) the excess of the market price of the shares on the
day the offering commenced over the price paid (in which case the balance of
the gain realized on sale will be treated as long-term capital gain) or (b)
the excess of the sale price over the price paid.
 
  If the participant sells the shares before he or she has owned them for more
than one year or before the expiration of a two-year period commencing on the
day the offering period commenced, the participant will have to recognize
ordinary income on the amount of the excess of the purchase price paid over
the market price of the shares on the date of purchase, and the Company will
receive an expense deduction for the same amount, subject to the limitations
imposed by Section 162(m) of the Code. The participant will recognize a
capital gain or loss (long- or short-term, depending on the period he has
owned the shares) for the excess of the sale price over the market value on
the date of purchase.
 
  Except as described in the preceding paragraph, the Company will not be
entitled to a tax deduction upon the purchase or sale of shares under the
Purchase Plan.
 
 401(K) SAVINGS AND RETIREMENT PLAN
 
  In 1995, the Company adopted a 401(k) Savings and Retirement Plan (the
"401(k) Plan"), a tax-qualified plan covering all of its employees who are at
least 21 years of age. Each employee may elect to reduce his or her current
compensation by up to 15%, subject to the statutory limit (a maximum of $9,500
in 1996) and have the amount of the reduction contributed to the 401(k) Plan.
The 401(k) Plan provides that the Company may, as determined from time to time
by the Board of Directors, provide a matching cash contribution. In addition,
the Company may contribute an additional amount to the 401(k) Plan, as
determined by the Board of Directors, which will be allocated based on the
proportion of the employee's compensation for the plan year to the aggregate
compensation for the plan year for all eligible employees.
 
  All employee and Company contributions to the 401(k) Plan are fully vested
at all times.

                             CERTAIN TRANSACTIONS
 
  Since 1993, the Company has engaged in the following transactions with the
following directors, officers and stockholders who beneficially own more than

RELATED PARTY TRANSACTIONS
 
 CONSULTING FEES AND PREFERRED STOCK ISSUANCE COSTS
 
  In February 1993, the Company entered into a consulting and financial
advisory agreement with KBL Healthcare, Inc., the selling agent involved with
the issuance of the Company's Series A Preferred Stock. Dr. Krauss, the Chief
Executive Officer of the selling agent, is Chairperson of the Company's Board
of Directors. Total fees paid under this agreement during 1994 and 1993 were
approximately $41,000 and $63,000, respectively. In addition, in conjunction
with the Series A Preferred Stock issuance in 1993, the Company paid the
selling agent approximately $648,000 in commissions and expenses and warrants
to purchase 328,904 shares of Common Stock at an exercise price of $2.00 per
share were issued to the selling agent. The warrants contain a cashless
exercise provision whereby the warrant holder can surrender in-the-money
warrants in exchange for a net number of shares of Common Stock based on the
fair market value of the Common Stock at the time of exercise.
 
  During 1995, the Company entered into an additional agreement with the
selling agent. Under this agreement, the Company obtained consulting and
financial advisory services in relation to the issuance of the Company's
Series B Preferred Stock. Total fees paid under this agreement during 1995
amounted to $87,500.
 
 SALE OF SERIES B PREFERRED STOCK
 
  In April 1995, the Company sold 1,546,612, 385,318 and 401,403 shares of
Series B Convertible Preferred Stock (convertible into 773,306, 192,659, and
200,702 of Common Stock, respectively) to Morgan Stanley Venture Capital Fund
II, L.P., Morgan Stanley Venture Capital Fund II, C.V. and Morgan Stanley
Venture Investors, L.P., respectively, at $1.50 per share, for aggregate
consideration of $3,500,000. Mr. Husain, a member of the Company's Board of
Directors, is a Vice President of Morgan Stanley & Co. Incorporated, an
affiliate of which is the managing general partner of such partnerships.
 
 CONSULTING AND TECHNOLOGY AGREEMENT/LICENSE AGREEMENT
 
  In February 1993, the Company entered into a consulting and technology
agreement with Dr. Cohen pursuant to which Dr. Cohen spends one day a week at
the Company working on the development and commercialization of the technology
licensed to the Company pursuant to the MIT License Agreements. This
agreement, which expires in February 1998, requires the Company to pay monthly
consulting fees of up to $12,500. Total payments made during 1995, 1994 and
1993 were approximately $100,000, $142,000 and $116,000, respectively. The
Company is also required to remit a royalty of 1% of net sales from products
and 7% of gross revenue from sublicenses derived by the Company from the
technologies licensed under the MIT License Agreements. In connection with
this agreement, a warrant to purchase 109,634 shares of Common Stock for $2.00
per share was issued to Dr. Cohen. During the term of the consulting
agreement, and for a period of up to two additional years following the
termination or expiration of this agreement, Dr. Cohen is obligated not to
compete with the Company so long as the Company makes continuing payments to
Dr. Cohen during such two year period.
 
  In February 1993, the Company also entered into a license agreement with Dr.
Cohen, pursuant to which Dr. Cohen granted to the Company an exclusive license
to certain cardiac output monitoring technology developed by Dr. Cohen. The
Cohen License Agreement provides that the Company must
 
                                      47
<PAGE>
 
achieve certain milestones, which include raising equity capital, spending a
minimum of $200,000 in each two-year period during the term of the agreement
and conducting clinical trials. If such milestones are not achieved, Dr. Cohen
has the right to terminate the agreement. The Cohen License Agreement also
sets forth certain provisions relating to potential infringement of the patent
rights that allow, but do not require, either party to take action against
such infringement. The Company is required to pay Dr. Cohen a royalty based on
3% of net sales of products developed from such technology. If the Company
chooses to sublicense this technology to an unrelated party, the royalty will
be based on 20% of the gross revenue received from the unrelated party for
products developed from such technology. This technology is at an early stage
of development and it is uncertain when, if at all, the Company will seek to
commercialize this technology.

                         DESCRIPTION OF CAPITAL STOCK
 
  Upon completion of the Offering, the Company will be authorized to issue
25,000,000 shares of Common Stock, $.001 par value per share of which
10,663,871 will be issued and outstanding, and 2,000,000 shares of
undesignated Preferred Stock, $.001 par value per share, of which no shares
will be issued and outstanding.
 
COMMON STOCK
 
  As of May 15, 1996 (after giving effect to the automatic conversion into
Common Stock of all outstanding shares of Preferred Stock upon the closing of
this Offering), there were 7,663,872 shares of Common Stock outstanding, held
of record by approximately 140 stockholders. Holders of Common Stock are
entitled to one vote for each share held on all matters submitted to a vote of
stockholders and do not have cumulative voting rights. Accordingly, holders of
a majority of the shares of Common Stock entitled to vote in any election of
directors may elect all of the directors standing for election. Holders of
Common Stock are entitled to receive ratably such dividends, if any, as may be
declared by the Board of Directors out of funds legally available therefor,
subject to any preferential dividend rights of outstanding Preferred Stock.
Upon the liquidation, dissolution or winding up of the Company, the holders of
Common Stock are entitled to receive ratably the net assets of the Company
available after the payment of all debts and other liabilities and subject to
the prior rights of any outstanding Preferred Stock. Holders of Common Stock
have no preemptive, subscription, redemption or conversion rights. The
outstanding shares of Common Stock are, and the shares offered by the Company
in this Offering will be, when issued and paid for, fully paid and
nonassessable. The rights, preferences and privileges of holders of Common
Stock are subject to, and may be adversely affected by, the rights of the
holders of shares of any series of Preferred Stock which the Company may
designate and issue in the future.
 
WARRANTS
 
  As of May 1, 1996, a total of 438,538 shares of Common Stock were issuable
upon exercise of outstanding warrants at an exercise price of $2.00 per share.
All of such warrants, unless exercised prior to May 1, 1996, will remain
outstanding after the closing of this Offering.
 
PREFERRED STOCK
 
  Upon the closing of this Offering, the Company's Restated Certificate of
Incorporation will authorize the issuance of up to 2,000,000 shares of
Preferred Stock, $.001 par value per share. Under the terms of the Restated
Certificate of Incorporation, the Board of Directors is authorized, subject to
any limitations prescribed by law, without stockholder approval, to issue such
shares of Preferred Stock in one or more series. Each such series of Preferred
Stock shall have such rights, preferences, privileges and restrictions,
including voting rights, dividend rights, conversion rights, redemption
privileges and liquidation preferences, as shall be determined by the Board of
Directors.
 
  The purpose of authorizing the Board of Directors to issue Preferred Stock
and determine its rights and preferences is to eliminate delays associated
with a stockholder vote on specific issuances. The issuance of Preferred
Stock, while providing desirable flexibility in connection with possible
acquisitions and other corporate purposes, could have the effect of making it
more difficult for a third party to acquire, or of discouraging a third party
from acquiring, a majority of the outstanding voting stock of the Company. The
Company has no present plans to issue any shares of Preferred Stock.
 
DELAWARE LAW AND CERTAIN CHARTER AND BY-LAW PROVISIONS
 
  The Company is subject to the provisions of Section 203 of the General
Corporation Law of Delaware. Section 203 prohibits a publicly held Delaware
corporation from engaging in a "business combination" with an "interested
stockholder" for a period of three years after the date of the transaction in
which the person became an interested stockholder, unless the business
combination is
 
                                      51
<PAGE>
 
approved in a prescribed manner. A "business combination" includes mergers,
asset sales and other transactions resulting in a financial benefit to the
interested stockholder. Subject to certain exceptions, an "interested
stockholder" is (i) a person who, together with affiliates and associates,
owns 15% or more of the corporation's voting stock or (ii) is an affiliate or
associate of the Company and was the owner, together with affiliates and
associates of 15% or more of the outstanding voting stock of the Company at
any time within the 3-year period prior to the date for determining whether
such person is "interested".
 
  The Restated Certificate of Incorporation provides for the division of the
Board of Directors into three classes as nearly equal in size as possible with
staggered three-year terms. See "Management--Executive Officers and
Directors". In addition, the Restated Certificate of Incorporation provides
that directors may be removed only for cause by the affirmative vote of the
holders of two-thirds of the shares of capital stock of the corporation
entitled to vote. Under the Restated Certificate of Incorporation, any vacancy
on the Board of Directors, however occurring, including a vacancy resulting
from an enlargement of the Board, may only be filled by vote of a majority of
the directors then in office. The classification of the Board of Directors and
the limitations on the removal of directors and filling of vacancies could
have the effect of making it more difficult for a third party to acquire, or
of discouraging a third party from acquiring, control of the Company.
 
  The Restated Certification of Incorporation also provides that after the
closing of this Offering, any action required or permitted to be taken by the
stockholders of the Company at an annual meeting or special meeting of
stockholders may only be taken if it is properly brought before such meeting
and may not be taken by written action in lieu of a meeting. The Restated
Certificate of Incorporation further provides that special meetings of the
stockholders may only be called by the President of the Company or by the
Board of Directors. Under the Company's By-Laws, as amended (the "By-Laws"),
in order for any matter to be considered "properly brought" before a meeting,
a stockholder must comply with certain requirements regarding advance notice
to the Company. The foregoing provisions could have the effect of delaying
until the next stockholders' meeting stockholder actions which are favored by
the holders of a majority of the outstanding voting securities of the Company.
These provisions may also discourage another person or entity from making a
tender offer for the Company's Common Stock, because such person or entity,
even if it acquired a majority of the outstanding voting securities of the
Company, would be able to take action as a stockholder (such as electing new
directors or approving a merger) only at a duly called stockholders' meeting,
and not by written consent.
 
  The General Corporation Law of Delaware provides generally that the
affirmative vote of a majority of the shares entitled to vote on any matter is
required to amend a corporation's Restated Certificate of Incorporation or By-
Laws, unless a corporation's Restated Certificate of Incorporation or By-Laws,
as the case may be, requires a greater percentage. The Restated Certificate of
Incorporation and the By-Laws require the affirmative vote of the holders of
at least 75% of the shares of capital stock of the Company issued and
outstanding and entitled to vote to amend or repeal any of the provisions
described in the prior two paragraphs.
 
  The Restated Certificate of Incorporation contains certain provisions
permitted under the General Corporation Law of Delaware relating to the
liability of directors. The provisions eliminate a director's liability for
monetary damages for a breach of fiduciary duty, except in certain
circumstances involving wrongful acts, such as the breach of a director's duty
of loyalty or acts or omissions which involve intentional misconduct or a
knowing violation of law. Further, the Restated Certificate of Incorporation
contains provisions to indemnify the Company's directors and officers to the
fullest extent permitted by the General Corporation Law of Delaware. The
Company believes that these provisions will assist the Company in attracting
and retaining qualified individuals to serve as directors.
 
TRANSFER AGENT AND REGISTRAR
 
  The transfer agent and registrar for the Common Stock is American Stock
Transfer & Trust Company.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Upon completion of this Offering there will be 10,663,871 shares of Common
Stock of the Company outstanding. There were also 1,062,037 shares covered by
vested options and warrants outstanding at May 15, 1996, which are not
considered to be outstanding shares. Of the outstanding shares, 3,225,028
shares, including the 3,000,000 shares of Common Stock sold in this Offering,
will be immediately eligible for resale in the public market without
restriction under the Securities Act, except that any shares purchased in this
Offering by affiliates of the Company ("Affiliates"), as that term is defined
in Rule 144 under the Securities Act ("Rule 144"), may generally only be
resold in compliance with applicable provisions of Rule 144. On October 25,
1996, an additional 1,832,864 shares of Common Stock, which are not subject to
lock-up agreements with the Underwriters, will be eligible for resale in the
public market in reliance on Rule 144(k) of the Securities Act. Beginning
approximately 90 days after the date of this Prospectus, approximately
4,930,147 additional shares of Common Stock (including approximately 542,960
shares covered by options exercisable within the 90-day period following the
date of this Prospectus) will become eligible for immediate resale in the
public market, subject to compliance as to certain of such shares with
applicable provisions of Rules 144 and 701.
 
  The Company, the executive officers and directors of the Company, and
certain security holders, have agreed pursuant to certain agreements that they
will not, without the prior written consent of the Representatives, offer,
sell or otherwise dispose of the shares of Common Stock beneficially owned by
them for a period of 180 days from the date of the Underwriting Agreement. The
shares subject to the lock-up agreements include approximately        of the
shares of Common Stock that would otherwise have become immediately eligible
for resale in the public market upon completion of this Offering,
approximately        of the shares of Common Stock that would otherwise have
become eligible for resale in the public market on October 25, 1996 and
approximately        of the shares of Common Stock (including approximately
       shares of Common Stock covered by options exercisable within the 90-day
period following the date of the Underwriting Agreement) that would otherwise
have become eligible for resale in the public market beginning approximately
90 days after the date of the Underwriting Agreement, subject to compliance as
to certain of such shares with the applicable provisions of Rules 144 and 701.
 
  In general, under Rule 144 as currently in effect, beginning approximately
90 days after the effective date of the Registration Statement of which this
Prospectus is a part, a stockholder, including an Affiliate, who has
beneficially owned his or her restricted securities (as that term is defined
in Rule 144) for at least two years from the later of the date such securities
were acquired from the Company or (if applicable) the date they were acquired
from an Affiliate is entitled to sell, within any three-month period, a number
of such shares that does not exceed the greater of 1% of the then outstanding
shares of Common Stock (approximately 106,639 immediately after this Offering)
or the average weekly trading volume in the Common Stock during the four
calendar weeks preceding the date on which notice of such sale was filed under
Rule 144, provided certain requirements concerning availability of public
information, manner of sale and notice of sale are satisfied. In addition,
under Rule 144(k), if a period of at least three years has elapsed between the
later of the date restricted securities were acquired from the Company or (if
applicable) the date they were acquired from an Affiliate of the Company, a
stockholder who is not an Affiliate of the Company at the time of sale and has
not been an Affiliate of the Company for at least three months prior to the
sale is entitled to sell the shares immediately without compliance with the
foregoing requirements under Rule 144. The Securities and Exchange Commission
has proposed an amendment to Rule 144 which would reduce the holding period
required for shares subject to Rule 144 to become eligible for sale in the
public market from two years to one year, and from three years to two years in
the case of Rule 144(k).
 
  Securities issued in reliance on Rule 701 (such as shares of Common Stock
that may be acquired pursuant to the exercise of certain options granted under
the 1993 Option Plan) are also restricted securities and, beginning 90 days
after the effective date of the Registration Statement of which this
 
                                      53
<PAGE>
 
Prospectus is a part, may be sold by stockholders other than an Affiliate of
the Company subject only to the manner of sale provisions of Rule 144 and by
an Affiliate under Rule 144 without compliance with its two-year holding
period requirement.
 
  At the completion of this Offering, certain persons and entities (the
"Rightholders"), will be entitled to certain rights with respect to the
registration under the Securities Act of a total of approximately 5,675,205
shares of Common Stock (the "Registrable Shares"), including 438,539 shares of
Common Stock that may be acquired pursuant to the exercise of outstanding
warrants (assuming an initial public offering price of $12.00 per share),
under the terms of agreements among the Company and the Rightholders (the
"Registration Agreements") and various outstanding warrants (the "Warrants",
and together with the Registration Agreement, the "Registration Instruments").
Pursuant to the Registration Instruments, certain Rightholders are entitled,
in the event the Company proposes to register any of its securities under the
Securities Act at any time, with certain exceptions, to include Registrable
Shares with respect to 5,675,205 shares of Common Stock in such registration,
subject to the right of the managing underwriter of any underwritten offering
to exclude from such registration for marketing reasons some or all of such
Registrable Shares. Pursuant to the Registration Instruments, certain
Rightholders have the right under certain circumstances to require the Company
to prepare and file registration statements under the Securities Act with
respect to a total of approximately 5,675,205 Registrable Shares, including
shares of Common Stock that may be acquired upon the exercise of outstanding
warrants, and the Company is required to use its best efforts to effect such
registration, subject to certain conditions and limitations. The Company is
generally required to bear the expense of all such registrations.
 
  Prior to this Offering, there has been no public market for the Common
Stock. No prediction can be made as to the effect, if any, that market sales
of shares or the availability of shares for sale will have on the market price
of the Common Stock prevailing from time to time. The Company is unable to
estimate the number of shares that may be sold in the public market pursuant
to Rule 144, since this will depend on the market price of the Common Stock,
the personal circumstances of the sellers and other factors. Nevertheless,
sales of significant amounts of the Common Stock of the Company in the public
market could adversely affect the market price of the Company's Common Stock
and could impair the Company's ability to raise capital through an offering of
its equity securities.
 
 
                                 LEGAL MATTERS
 
  The validity of the shares of Common Stock offered hereby will be passed
upon for the Company by Hale and Dorr, Boston, Massachusetts and for the
Underwriters by Shearman & Sterling, New York, New York.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders of
Cambridge Heart, Inc.
 
The 1-for-2 reverse stock split described in Note 5 to the financial
statements has not been consummated at May 30, 1996. When it has been
consummated, we will be in a position to furnish the following report:
 
   "In our opinion, the accompanying balance sheet and the related
   statements of operations, of changes in stockholders' equity (deficit)
   and of cash flows present fairly, in all material respects, the financial
   position of Cambridge Heart, Inc. (a development stage enterprise) at
   December 31, 1995 and 1994, and the results of its operations and its
   cash flows for each of the three years in the period ended December 31,
   1995, and for the period from inception (January 16, 1990) through
   December 31, 1995, in conformity with generally accepted accounting
   principles. These financial statements are the responsibility of the
   Company's management; our responsibility is to express an opinion on
   these financial statements based on our audits. We conducted our audits
   of these statements in accordance with generally accepted auditing
   standards which require that we plan and perform the audit to obtain
   reasonable assurance about whether the financial statements are free of
   material misstatement. An audit includes examining, on a test basis,
   evidence supporting the amounts and disclosures in the financial
   statements, assessing the accounting principles used and significant
   estimates made by management, and evaluating the overall financial
   statement presentation. We believe that our audits provide a reasonable
   basis for the opinion expressed above."

                         NOTES TO FINANCIAL STATEMENTS
 
1. THE COMPANY
 
  Cambridge Heart, Inc. (the "Company") was incorporated in Delaware on
January 16, 1990 and is engaged in the research, development and
commercialization of products for the non-invasive diagnosis of cardiac
disease. The Company intends to sell its products primarily to hospitals,
research institutions and cardiovascular specialists.
 
  During the period from inception (January 16, 1990) through December 31,
1995, the Company devoted substantially all of its efforts to business
planning, raising financing, recruiting personnel, research and development
and obtaining regulatory approval for its products. Although the Company
commenced its planned principal activities and began selling its products in
1995, it has not generated significant revenue therefrom. Accordingly, the
Company is considered to be in the development stage, as defined in Statement
of Financial Accounting Standards No. 7, at December 31, 1995.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Significant accounting policies followed by the Company in the preparation
of its financial statements are as follows:
 
 CASH AND CASH EQUIVALENTS
 
   The Company considers all highly liquid debt instruments purchased with an
 original maturity of three months or less to be cash equivalents. The Company
 invests its excess cash primarily in money market accounts and short-term
 commercial paper of companies with strong credit ratings and in diversified
 industries. Accordingly, these investments are subject to minimal credit and
 market risk. The investments held at December 31, 1995 are classified as held
 to maturity, and all mature within thirty-five days of December 31, 1995.
 These investments have been recorded at amortized cost, which approximates
 fair market value. No realized or unrealized gains or losses have been
 recognized.
 
 INVENTORIES
 
   Inventories, consisting primarily of purchased components, are stated at
 the lower of cost or market. Cost is determined using the first-in, first-out
 (FIFO) method.
 
 FIXED ASSETS
 
   Equipment, furniture and sales display items are stated at cost, less
 accumulated depreciation. Depreciation is provided using the straight-line
 method based on estimated useful lives. Repair and maintenance costs are
 expensed as incurred.
 
 REVENUE RECOGNITION
 
   Revenue is recognized upon shipment of goods. Revenue from a research and
 option arrangement is recognized pursuant to the agreement as the work is
 performed.
 
 RESEARCH AND DEVELOPMENT
 
   Research, engineering and product development costs are expensed as
 incurred. Software development costs that would otherwise be capitalizable
 under Statement of Financial Accounting Standards No. 86, "Accounting for the
 Costs of Computer Software to be Sold, Leased, or Otherwise Marketed," have
 not been material to date.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)
 
 INCOME TAXES
 
   The Company utilizes the liability method of accounting for income taxes,
 as set forth in Statement of Financial Accounting Standards No. 109,
 "Accounting for Income Taxes." Under this method, deferred tax liabilities
 and assets are recognized for the expected future tax consequences of
 temporary differences between the carrying amounts and the tax bases of
 assets and liabilities.
 
 USE OF ESTIMATES
 
   The preparation of financial statements in conformity with generally
 accepted accounting principles requires management to make estimates and
 assumptions that affect the reported amount of assets and liabilities and
 disclosure of contingencies at December 31, 1994 and 1995, and the reported
 amounts of revenues and expenses during the three years in the period ended
 December 31, 1995 and for the period from inception (January 16, 1990)
 through December 31, 1995. Actual results could differ from these estimates.
 
 UNAUDITED PRO FORMA NET LOSS PER SHARE
 
   Unaudited pro forma net loss per share is determined by dividing net loss
 by the weighted average number of common shares and common share equivalents
 outstanding during the period. Common share equivalents, comprised of common
 stock options and warrants and convertible preferred stock, have been
 excluded from the calculation as their effect is anti-dilutive, except that,
 pursuant to Securities and Exchange Commission Staff Accounting Bulletin No.
 83, common share equivalents issued and common stock sold at prices below the
 offering price in the twelve months preceding the anticipated public offering
 have been included in the calculation as if outstanding for all periods
 presented.
 
   As described in Note 5, conversion of all convertible preferred stock will
 occur upon the closing of a qualified public offering of the Company's common
 stock. The unaudited pro forma net loss per share information included in the
 accompanying statement of operations for the year ended December 31, 1995 and
 for the three months ended March 31, 1996 reflects the impact on unaudited
 pro forma net loss per share of such conversion as of the beginning of each
 period or date of issuance, if later, using the if-converted method.
 
   Historical net loss per share has not been presented on the basis that it
 is irrelevant due to the significant change in the Company's capital
 structure and resultant earnings or loss per share which will result upon
 conversion of the convertible preferred stock.
 
 UNAUDITED INTERIM FINANCIAL DATA
 
   The interim financial data as of March 31, 1996 and for the three months
 ended March 31, 1995 and 1996 and for the period from inception (January 16,
 1990) through March 31, 1996 are unaudited; however, in the opinion of
 management, the interim financial data include all adjustments, consisting
 only of normal recurring adjustments, necessary for a fair presentation of
 the results of operations for these interim periods. The interim financial
 data are not necessarily indicative of the results of operations for a full
 fiscal year.

 RECENTLY ENACTED ACCOUNTING STANDARDS
 
   In October 1995, the Financial Accounting Standards Board issued Statement
 of Financial Accounting Standards No. 123, "Accounting for Stock-based
 Compensation." The Company has elected to adopt this standard in 1996 through
 footnote disclosure only.

5. STOCKHOLDERS' EQUITY (DEFICIT)
 
 REVERSE COMMON STOCK SPLIT
 
   On May 29, 1996, the Board of Directors authorized a 1-for-2 reverse stock
 split of the Company's common stock which will become effective prior to the
 closing date of the Company's initial public offering. All shares of common
 stock, common stock options and warrants, preferred stock conversion ratios
 and per share amounts included in the accompanying financial statements have
 been adjusted to give retroactive effect to the reverse stock split for all
 periods presented.
 
 CONVERTIBLE PREFERRED STOCK
 
   The Company has authorized 10,400,000 shares of preferred stock, of which
 6,900,000 shares have been designated as Series A convertible preferred stock
 ("Series A Preferred Stock") and 2,500,000 shares have been designated as
 Series B convertible preferred stock ("Series B Preferred Stock"). The
 remaining authorized shares have not been designated. The preferred stock has
 the following characteristics:
 
                                      F-9

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)

5. STOCKHOLDERS' EQUITY (DEFICIT)--(CONTINUED)
 
  Conversion
 
   Each share of preferred stock is convertible at any time at the option of
 the holder into shares of common stock pursuant to a ratio of one share of
 common stock for two shares of preferred stock, subject to certain stock
 split and stock dividend adjustments. In addition, the conversion ratio is
 subject to adjustment, as defined in the respective agreements, in the event
 that the Company issues common stock at a per share price less than $3.00 and
 $2.00 per share for the Series B Preferred Stock and the Series A Preferred
 Stock, respectively. All preferred stock will automatically convert to common
 stock upon the earlier of i) the closing of a public offering of the
 Company's common stock involving aggregate proceeds of at least $10,000,000
 and a per share price of not less than $6.00, or ii) the consent of the
 holders of at least 51% of the then outstanding shares of preferred stock.
 
   At December 31, 1995, the Company has reserved 1,166,667 and 3,289,041
 shares of common stock for issuance upon the conversion of the Series B
 Preferred Stock and the Series A Preferred Stock, respectively.
 
  Dividends
 
   Dividends on the preferred stock are payable prior and in preference to any
 declaration or payment of any dividend on the common stock of the Company
 when, as and if declared by the Board of Directors of the Company. Through
 December 31, 1995 and March 31, 1996, no dividends have been declared or paid
 by the Company.
 
  Liquidation Preference
 
   In the event of any liquidation, dissolution or winding up of the affairs
 of the Company, the holders of the Series B Preferred Stock will be entitled
 to receive in preference to the holders of the Series A Preferred Stock and
 the common stock an amount per share equal to $1.50. Subsequent to the
 repayment of the holders of the Series B Preferred Stock, the holders of the
 Series A Preferred Stock will be entitled to receive in preference to the
 holders of the common stock an amount per share equal to $1.00.
 
  Voting Rights
 
   Each holder of preferred stock is entitled to the number of votes equal to
 the number of shares of common stock into which such holder's shares are
 convertible at the date such vote is taken.
 
 CONVERSION OF NOTES PAYABLE
 
   During 1993, the Company issued convertible notes payable totaling $100,000
 to common stockholders. These notes bore interest at 8% per annum. The
 principal amount of these borrowings were converted into 100,000 shares of
 Series A Preferred Stock in September 1993.
 
 WARRANTS
 
   In connection with the Series A Preferred Stock issuance, warrants to
 purchase 328,904 shares of common stock were issued to the Company's selling
 agent, a related party (Note 11). The warrants were issued with an exercise
 price of $2.00 per share and expire in September 1998. The warrants contain a
 cashless exercise provision whereby the warrant holder can surrender in-the-
 money warrants in exchange for a net number of shares of Common Stock based
 on the fair maket value of the Common Stock at the date of exercise. At
 December 31, 1995, the Company has reserved 328,904 shares of common stock
 for issuance upon the exercise of these warrants.

5. STOCKHOLDERS' EQUITY (DEFICIT)--(CONTINUED)
 
   In addition, warrants to purchase 109,634 shares of common stock were
 issued in February 1993 to a related party who provides consulting services
 to the Company (Note 11). These warrants were issued with an exercise price
 of $2.00 per share and expire on September 24, 1998. At December 31, 1995,
 the Company has reserved 109,634 shares of common stock for issuance upon the
 exercise of these warrants.
 
   The value of the above warrants at the time of issuance was estimated by
 management and determined not to be material to the Company's results of
 operations and financial position.
 
 STOCK RESTRICTIONS
 
   During 1995, the Company entered into amended agreements with the holders
 of all issued shares of common stock, 2,500,000 shares of Series A Preferred
 Stock and 2,333,333 shares of Series B Preferred Stock, under which the
 Company retains the right of first refusal to purchase any such shares
 offered for sale. These agreements terminate upon the earlier of the closing
 of a public offering of the Company's common stock involving aggregate
 proceeds of at least $10,000,000 and a per share price of not less than
 $6.00, such time as the holders of the Series A Preferred Stock hold fewer
 than 800,000 shares of Series A Preferred Stock and/or common stock issued on
 conversion thereof, or such time as the holders of the Series B Preferred
 Stock hold fewer than 746,000 shares of Series B Preferred Stock and/or
 common stock issued on conversion thereof.
 
 STOCK PURCHASE RIGHT
 
   In February 1993, the Company entered into an option agreement with a third
 party giving the Company an option to enter into certain license agreements.
 In connection with the option agreement, a right to purchase 180,000 shares
 of the Company's common stock at a price of $0.002 per share was granted to
 the third party. The right became exercisable immediately when the Company
 entered into such license agreements in September 1993. The estimated fair
 value of this right, $35,640, was expensed and recorded as additional paid-
 in-capital. The right was exercised, and shares issued, in December 1993.
 
 NEWLY AUTHORIZED COMMON AND PREFERRED STOCK
 
   On May 29, 1996, the Company's Board of Directors increased, subject to
 stockholders approval, the number of authorized shares of the Company's
 $0.001 par value common stock to 25,000,000 and authorized an additional
 2,000,000 shares of the Company's $0.001 par value preferred stock. The newly
 authorized preferred stock may be issued at the discretion of the Board of
 Directors of the Company (without stockholder approval) with such
 designations, rights and preferences as the Board of Directors may determine
 from time to time. This preferred stock may have dividend, liquidation,
 redemption, conversion, voting or other rights which may be more expansive
 than the rights of the holders of the common stock.

6. STOCK PLANS
 
 1993 INCENTIVE AND NON-QUALIFIED STOCK OPTION PLAN
 
   During 1993, the Company adopted the 1993 Incentive and Non-Qualified Stock
 Option Plan (the "1993 Plan"). The 1993 Plan provides for the granting of
 incentive and non-qualified stock options to management, other key employees,
 consultants and directors of the Company. The total number of shares of
 common stock that may be issued pursuant to the exercise of options granted
 under the 1993 Plan is 1,688,663. Incentive stock options may not be granted
 at less than fair market value of the Company's common stock at the date of
 grant and for a term not to exceed ten years. For holders of more than 10% of
 the Company's total combined voting power of all classes of stock, incentive
 stock options may not be granted at less than 110% of the fair market value
 of the Company's common stock at the date of grant and for a term not to
 exceed five years. The exercise price under each non-qualified stock option
 shall be specified by the stock option committee, but shall in no case be
 less than the par value of the common stock subject to the non-qualified
 stock option.
 
   A summary of plan activity is as follows:

   At December 31, 1995, 1,480,500 shares of common stock are reserved for
 issuance upon exercise of the options issued under the 1993 Plan.
 
   On March 18 and 25, 1996, the Company granted stock options to purchase
 8,750 and 56,250 shares of its common stock, respectively, at exercise prices
 of $4.00 and $1.00 per share, respectively, to certain employees. The Company
 has recorded deferred compensation of $428,750, representing the difference

 grant ($8.00) and the exercise price. Deferred compensation related to these
 options is recorded as a reduction of stockholders' equity and will be
 amortized ratably over the option vesting period of five years.

6. STOCK PLANS--(CONTINUED)
 
 1996 EQUITY INCENTIVE PLAN
 
   On May 29, 1996, the Board of Directors authorized, subject to stockholder
 approval, the 1996 Equity Incentive Plan (the "Incentive Plan"). The
 Incentive Plan provides for the issuance of up to 1,000,000 shares of the
 Company's common stock to eligible employees, officers, directors,
 consultants and advisors of the Company. Under the Incentive Plan, the Board
 of Directors may award incentive and non-qualified stock options, stock
 appreciation rights, performance shares and restricted and unrestricted
 stock.
 
   Incentive stock options may not be granted at less than fair market value
 of the Company's common stock at the date of grant and for a term not to
 exceed ten years. For holders of more than 10% of the Company's total
 combined voting power of all classes of stock, incentive stock options may
 not be granted at less than 110% of the fair market value of the Company's
 common stock at the date of grant and for a term not to exceed five years.
 The exercise price under each non-qualified stock option shall be specified
 by the stock option committee, but shall in no case be less than the par
 value of the common stock subject to the non-qualified stock option. Grants
 of stock appreciation rights, performance shares, restricted stock and
 unrestricted stock may be made at the discretion of the Board of Directors
 with terms to be defined therein except that the exercise and transfer of
 stock appreciation rights granted in tandem with stock options is limited by
 the terms of the related options.
 
 1996 DIRECTOR OPTION PLAN
 
   On May 29, 1996, the Board of Directors authorized, subject to stockholder
 approval, the issuance of up to 100,000 shares of the Company's common stock
 pursuant to its 1996 Director Option Plan (the "Director Plan"). Under the
 Director Plan, outside directors of the Company who are not otherwise
 affiliated with the Company are entitled to receive options to purchase
 10,000 shares of common stock upon their initial election to the Board of
 Directors. In addition, three existing outside directors will be granted
 options to purchase 10,000 shares of common stock upon completion of the
 Company's initial public offering. All option grants made under the Director
 Plan have exercise prices equal to the fair market value of the Company's
 common stock on the date of grant, and will vest in three annual installments
 on the anniversary date of the grant. Director options will become
 immediately exercisable upon the occurrence of a change in control (as
 defined in the Director Plan).
 
 1996 EMPLOYEE STOCK PURCHASE PLAN
 
   On May 29, 1996, the Board of Directors authorized, subject to stockholder
 approval, the 1996 Employee Stock Purchase Plan (the "Purchase Plan"). The
 Purchase Plan provides for the issuance of up to 100,000 shares of the
 Company's common stock to eligible employees. Under the Purchase Plan, the
 Company is authorized to make one or more offerings during which employees
 may purchase shares of common stock through payroll deductions made over the
 term of the offering. The term of individual offerings, which are set by the
 Board of Directors, may be for periods of twelve months or less and may be
 different for each offering. The per-share purchase price at the end of each
 offering is equal to 85% of the fair market value of the common stock at the
 beginning or end of the offering period (as defined by the Purchase Plan),
 whichever is lower. The first offering period will commence upon completion
 of the Company's initial public offering

7. RESEARCH AND OPTION AGREEMENT
 
  In April 1994, the Company entered into a research and option agreement with
a third party whereby the third party has agreed to fund $50,000 for certain
research and development activities. Under this agreement, which has multiple
phases to be perfomed by both the Company and the third party, the third party
has the option to obtain an exclusive or non-exclusive license to sell
products using technology developed by the Company, at which time the third
party would be obligated to pay royalties to the Company on sales of the
related products. Royalty rates would range from .375% to .75% of net sales of
the related products (depending upon whether the license is non-exclusive or
exclusive, respectively) with various minimum and maximum amounts. Amounts
received relating to this agreement have been included as revenue in the
statement of operations and the related costs have been included in research
and development expense. This agreement may be terminated by the third party
at any time.

  The Company has generated taxable losses from operations since inception
and, accordingly, has no taxable income available to offset the carryback of
net operating losses. In addition, although management's operating plans
anticipate taxable income in future periods, such plans provide for taxable
losses over the near term and make significant assumptions which cannot be
reasonably assured including approval of the Company's products by the U.S.
Food and Drug Administration and market acceptance of the Company's products
by customers. Based upon the weight of all available evidence, the Company has
provided a full valuation allowance for its deferred tax assets since, in the
opinion of management, realization of these future benefits is not
sufficiently assured (defined as a likelihood of slightly more than 50
percent).

  An ownership change, as defined in the Internal Revenue Code, resulting from
the Company's issuance of additional stock may limit the amount of net
operating loss and tax credit carryforwards that can be utilized annually to
offset future taxable income and tax liabilities. The amount of the annual
limitation is determined based upon the Company's value immediately prior to
the ownership change. Subsequent significant changes in ownership could
further affect the limitation in future years.
 
9. SAVINGS PLAN
 
  In January 1995, Cambridge Heart adopted a retirement savings plan for all
employees pursuant to Section 401 (k) of the Internal Revenue Code. Employees
become eligible to participate on the first day of the calendar quarter
following their hire date. Employees may contribute any whole percentage of
their salary, up to a maximum annual statutory limit. The Company is not
required to contribute to this plan. The Company made no contributions to this
plan in 1995.

 terminated at the sole option of the licensor. License maintenance fees paid
 during 1995 amounted to $20,000. No license maintenance fees were paid during
 1993 and 1994. The future minimum license maintenance fee commitments at

11. RELATED PARTY TRANSACTIONS, INCLUDING ROYALTY OBLIGATIONS
 
 CONSULTING FEES AND PREFERRED STOCK ISSUANCE COSTS
 
   In February 1993, the Company entered into a consulting and financial
 advisory agreement with the selling agent involved with the Company's Series
 A Preferred Stock issuance (Note 5). The Chief Executive Officer of the
 selling agent is Chairperson of the Company's Board of Directors. Total cash
 fees paid under this agreement during 1994 and 1993 were approximately
 $41,000 and $63,000, respectively. In addition, in conjunction with the
 Series A Preferred Stock issuance in 1993, the Company paid the selling agent
 approximately $648,000 in commissions and expenses and warrants to purchase
 328,904 shares of common stock were issued to the selling agent (Note 5).
 
   During 1995, the Company entered into an additional agreement with the
 selling agent. Under this agreement, the Company obtained consulting and
 financial advisory services in relation to the issuance of the Company's
 Series B Preferred Stock issuance (Note 5). Total fees paid under this
 agreement during 1995 amounted to $87,500.
 
 LICENSE AGREEMENT/CONSULTING AND TECHNOLOGY AGREEMENT
 
   In February 1993, the Company entered into a license agreement with a
 member of the Company's Board of Directors. This individual is also Chairman
 of the Company's Scientific Advisory Board and a faculty member at the
 institution with which the Company has entered into certain other license
 agreements. In exchange for exclusive patented technology licensing rights,
 the Company is required to pay this individual a royalty based on 3% of net
 sales of products developed from such technology. If the Company chooses to
 sublicense this product to an unrelated party, the royalty will be based on
 20% of the gross revenue received from the unrelated party for products
 developed from such technology. Additionally, the Company is required to
 spend a minimum of $200,000 in each two-year period for research and
 development, clinical trials, marketing, sales and/or manufacturing of
 products related to this technology. Should the Company fail to meet this
 requirement, the license agreement may be terminated at the sole option of
 the licensor.
 
   Also in February 1993, the Company entered into a consulting and technology
 agreement with this individual. This agreement, which expires in February
 1998, requires the Company to pay monthly consulting fees of either $7,500 or
 $12,500, as stipulated in the agreement. Total payments made during 1993,
 1994 and 1995 were approximately $116,000, $142,000 and $100,000,
 respectively, and are included in research and development expense. The
 Company is also required to remit to this individual a royalty of 1% of net
 sales of products developed from certain other technology licensed from the
 institution described above. If the Company chooses to sublicense such
 products to an unrelated party, the royalty will be based on 7% of the gross
 revenue received from the unrelated party for products developed from such
 technology. In connection with this consulting and technology agreement, a
 warrant to purchase 109,634 shares of common stock was issued (Note 5) to
 this individual.
 
   Operations through December 31, 1995 and March 31, 1996 did not result in
 the recognition of any material royalty expense in connection with these
 agreements.
 
12. MAJOR CUSTOMERS AND EXPORT SALES
 
  During 1995, the Company derived all product revenues from a distributor of
the Company's products in Japan. There was no product revenue prior to 1995.

  Under the terms and conditions of the U.S. Underwriting Agreement, the U.S.
Underwriters are committed to take and pay for all of the shares offered
hereby, if any are taken.
 
  The U.S. Underwriters propose to offer the shares of Common Stock in part
directly to the public at the initial public offering price set forth on the
cover page of this Prospectus, and in part to certain securities dealers at
such price less a concession of $   per share. The U.S. Underwriters may
allow, and such dealers may reallow, a concession not in excess of $   per
share to certain brokers and dealers. After the shares of Common Stock are
released for sale to the public, the offering price and other selling terms
may from time to time be varied by the representatives.
 
  The Company has entered into an underwriting agreement (the "International
Underwriting Agreement") with the underwriters of the International Offering
(the "International Underwriters") providing for the concurrent offer and sale
of 600,000 shares of Common Stock in an International Offering outside the
United States. The offering price and aggregate underwriting discounts and
commissions per share for the Offerings are identical. The closing of the U.S.
Offering made hereby is a condition to the closing of the International
Offering, and vice versa. The representatives of the International
Underwriters are Goldman Sachs International, an affiliate of Goldman, Sachs &
Co. and Bear, Stearns International Limited, an affiliate of Bear, Stearns &
Co., Inc.
 
  Pursuant to an Agreement between the U.S. and International Underwriting
Syndicates (the "Agreement Between Syndicates") relating to the Offerings,
each of the U.S. Underwriters named herein has agreed or will agree that, as
part of the distribution of the shares offered hereby and subject to certain
exceptions, it will offer, sell or deliver the shares offered hereby and any
other shares of Common Stock, directly or indirectly, only in the United
States (including the States and the District of Columbia), its territories,
its possessions and other areas subject to its jurisdiction (the "United
States") and to U.S. persons, which term shall mean, for purposes of this
paragraph: (a) any individual who is a resident of the United States or (b)
any corporation, partnership or other entity organized in or under the laws of
the United States or any political subdivision thereof and whose office most
directly involved with the purchase is located in the United States. Each of
the International Underwriters has agreed or will agree pursuant to the
Agreement between Syndicates that, as part of the distribution of the shares
offered as a part of the International Offering, and subject to certain
exceptions, it will (i) not, directly or indirectly, offer, sell or deliver
shares of Common Stock (a) in the United States or to any U.S. persons or (b)
to any person whom it believes intends to reoffer, resell or deliver the
shares in the United States or to any U.S. persons, and (ii) cause any dealer
to whom it may sell such shares at any concession to agree to observe a
similar restriction.
 
                                      U-1
<PAGE>
 
  Pursuant to the Agreement Between Syndicates, sales may be made between the
U.S. Underwriters and the International Underwriters of such number of shares
of Common Stock as may be mutually agreed. The price of any shares so sold
shall be the initial public offering price, less an amount not greater than
the selling concession.
 
  This Prospectus may be used by underwriters and dealers in connection with
offers and sales of the Common Stock, including shares initially sold in the
International Offering, to persons located in the United States.
 
  The Company has granted the U.S. Underwriters an option exercisable for 30
days after the date of this Prospectus to purchase up to an aggregate of
360,000 additional shares of Common Stock solely to cover over-allotments, if
any. If the U.S. Underwriters exercise their over-allotment option, the U.S.
Underwriters have severally agreed, subject to certain conditions, to purchase
approximately the same percentage thereof that the number of shares to be
purchased by each of them, as shown in the foregoing table, bears to the
2,400,000 shares of Common Stock offered in the U.S. Offering. The Company has
granted the International Underwriters a similar option to purchase up to an
aggregate of 90,000 shares of Common Stock.
 
  The Company has agreed during the period beginning from the date of this
Prospectus and continuing to and including the date 180 days after the date of
the Prospectus, not to offer, sell, contract to sell or otherwise dispose of
any securities of the Company (other than pursuant to employee stock option
plans existing, or on the conversion or exchange of convertible or
exchangeable securities outstanding, on the date of this Prospectus) which are
substantially similar to the shares of Common Stock or which are convertible
or exchangeable into securities which are substantially similar to the shares
of Common Stock, without the prior written consent of the representatives,
except for the shares of Common Stock offered in connection with the Offering.
The Company's executive officers and directors and certain other holders of
Common Stock who will hold in the aggregate     shares of Common Stock
following this Offering, have agreed not to offer, sell, contract to sell,
grant any option to purchase or otherwise dispose of or agree to dispose of
any shares of Common Stock or substantially similar securities owned
beneficially by them during the period beginning from the date of this
Prospectus and continuing to and including the date 180 days after the date of
this Prospectus, without the prior written consent of the representatives of
the Underwriters. See "Shares Eligible for Future Sale".
 
  The representatives of the Underwriters have informed the Company that they
do not expect sales to accounts over which the Underwriters exercise
discretionary authority to exceed five percent of the total number of shares
of Common Stock offered by them.
 
  Prior to the Offerings, there has been no public market for the Common
Stock. The initial public offering price will be negotiated among the Company
and the representatives of the Underwriters. Among the factors to be
considered in determining the initial public offering price of the Common
Stock, in addition to prevailing market conditions, will be the Company's
historical performance, estimates of the business potential and earnings
prospects of the Company, an assessment of the Company's management and the
consideration of the above factors in relation to market valuation of
companies in related businesses.
 
  The Company has applied for quotation of the Common Stock on the Nasdaq
National Market under the symbol "CAMH".
 
  The Company has agreed to indemnify the several Underwriters against certain
liabilities including liabilities under the Securities Act of 1933.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Article Nine of the Registrant's Restated Certificate of Incorporation (the
"Restated Certificate of Incorporation") provides that no director of the
Registrant shall be personally liable for any monetary damages for any breach
of fiduciary duty as a director, except to the extent that the Delaware
General Corporation Law prohibits the elimination or limitation of liability
of directors for breach of fiduciary duty.
 
  Article Nine of the Registrant's Restated Certificate of Incorporation
provides that a director or officer of the Registrant (a) shall be indemnified
by the Registrant against all expenses (including attorneys' fees), judgments,
fines and amounts paid in settlement incurred in connection with any
litigation or other legal proceeding (other than an action by or in the right
of the Registrant) brought against him by virtue of his position as a director
or officer of the Registrant if he acted in good faith and in a manner he
reasonably believed to be in, or not opposed to, the best interests of the
Registrant, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful and (b) shall be
indemnified by the Registrant against all expenses (including attorneys' fees)
and amounts paid in settlement incurred in connection with any action by or in
the right of the Registrant brought against him by virtue of his position as a
director or officer of the Registrant if he acted in good faith and in a
manner he reasonably believed to be in, or not opposed to, the best interests
of the Registrant, except that no indemnification shall be made with respect
to any matter as to which such person shall have been adjudged to be liable to
the Registrant, unless a court determines that, despite such adjudication but
in view of all of the circumstances, he is entitled to indemnification of such
expenses. Notwithstanding the foregoing, to the extent that a director or
officer has been successful, on the merits or otherwise, including, without
limitation, the dismissal of an action without prejudice, he is required to be
indemnified by the Registrant against all expenses (including attorneys' fees)
incurred in connection therewith. Expenses shall be advanced to a director or
officer at his request, provided that he undertakes to repay the amount
advanced if it is ultimately determined that he is not entitled to
indemnification for such expenses.
 
                                     II-1
<PAGE>
 
  Indemnification is required to be made unless the Registrant determines that
the applicable standard of conduct required for indemnification has not been
met. In the event of a determination by the Registrant that the director or
officer did not meet the applicable standard of conduct required for
indemnification, or if the Registrant fails to make an indemnification payment
within 60 days after such payment is claimed by such person, such person is
permitted to petition the court to make an independent determination as to
whether such person is entitled to indemnification. As a condition precedent
to the right of indemnification, the director or officer must give the
Registrant notice of the action for which indemnity is sought and the
Registrant has the right to participate in such action or assume the defense
thereof.
 
  Section 145 of the Delaware General Corporation Law provides that a
corporation has the power to indemnify a director, officer, employee or agent
of the corporation and certain other persons serving at the request of the
corporation in related capacities against amounts paid and expenses incurred
in connection with an action or proceeding to which he is or is threatened to
be made a party by reason of such position, if such person shall have acted in
good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and, in any criminal proceeding, if
such person had no reasonable cause to believe his conduct was unlawful;
provided that, in the case of actions brought by or in the right of the
corporation, no indemnification shall be made with respect to any matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the adjudicating court determines that such
indemnification is proper under the circumstances.
 
  Under Section Eight of the Underwriting Agreement, the Underwriters are
obligated, under certain circumstances, to indemnify directors and officers of
the Registrant against certain liabilities, including liabilities under the
Securities Act of 1933, as amended (the "Securities Act").

ITEM 17. UNDERTAKINGS
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions contained in the Restated Certificate of
Incorporation and Amended and Restated By-Laws of the Registrant and the laws
of the State of Delaware, or otherwise, the Registrant has been advised that
in the opinion of the Securities and Exchange Commission such indemnification
is against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities
being registered, the Registrant will, unless in the opinion of its counsel
the matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed
by the final adjudication of such issue.
 
  The undersigned Registrant hereby undertakes to provide to the Underwriters
at the closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
  The undersigned Registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of prospectus filed as part of this
  Registration Statement in reliance upon Rule 430A and contained in a form
  of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
  497(h) under the Securities Act shall be deemed to be part of this
  Registration Statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities
  Act, each post-effective amendment that contains a form of prospectus shall
  be deemed to be a new registration statement relating to the securities
  offered therein, and the offering of such securities at that time shall be
  deemed to be the initial bona fide offering thereof.

         ---------------- 
of stock to be designated, respectively, "Common Stock" and "Preferred Stock."
The total number of shares which the Corporation is authorized to issue is

     B.  Rights, Preferences and Restrictions of Preferred Stock.  The Preferred
         -------------------------------------------------------  
Stock authorized by this Restated Certificate of Incorporation may be issued 
from time to time in


                                      -2-
<PAGE>
 
one or more series.  The voting powers, designations, preferences and other 
special rights, and qualifications, limitations, or restrictions thereof, of the
Series A Preferred Stock and the Series B Preferred Stock are as set forth below
in this Article IV(B). The Board of Directors is hereby expressly vested with
the authority to determine and fix in the resolution or resolutions providing
for the issuance of additional series of Preferred Stock the voting powers, full
or limited, or no voting powers, and such designations, preferences and
relative, participating, optional, or other special rights (including conversion
or exchange rights), and qualifications, limitations, or restrictions thereof,
of each such series to the full extent now or hereafter permitted by the laws of
the State of Delaware. The Board of Directors is also authorized to increase or
decrease the number of shares of any series (other than the Series A Preferred
Stock or Series B Preferred Stock), prior or subsequent to the issue of that
series, but not below the number of shares of such series then outstanding. In
case the number of shares of any series shall be so decreased, the shares
constituting such decrease shall resume the status which they had prior to the
adoption of the resolution originally fixing the number of shares of such
series.

               1.  Dividend Provisions.  The Company shall not declare, or pay, 
                   ------------------- 
any cash dividends on any Common Stock or Preferred Stock of the Company without
the prior written consent of the holders of Series A Preferred Stock and Series 
B Preferred Stock, voting together as a class.  Subject to the rights of any 
other series of Preferred Stock that may from time to time come into existence, 
the holders of shares of Series A Preferred Stock and the holders of shares of 
Series B Preferred Stock (on an as converted basis) together with the holders of
Common Stock, shall be entitled to receive dividends, on a pari passu basis, out
                                                           ---- -----
of any assets legally available therefor, prior and in preference to any 
declaration or payment of any dividend on any junior securities of the 
Corporation, when, as and if declared by the Board of Directors.  No dividends 
shall be payable upon any junior securities of the Corporation unless 
equivalent dividends, on an as converted basis, are declared and paid 
concurrently on the Series A Preferred Stock, the Series B Preferred Stock and 
the Common Stock.

               2.  Liquidation Preference.
                   ----------------------

                    (a)  Series B Preferred Stock.  In the event of any 
                         ------------------------
liquidation, dissolution or winding up of the Corporation, either voluntary or 
involuntary, the holders of Series B Preferred Stock shall be entitled to 
receive, prior and in preference to any distribution of any of the assets of the
Corporation to the holders of Series A Preferred Stock or Common Stock by reason
of their ownership thereof, an amount per share equal to $1.50 (as adjusted for 
stock splits, combinations or

                                      -3-

<PAGE>
 

similar events) for each outstanding share of Series B Preferred Stock plus an 
amount equal to all dividends declared but theretofore unpaid. If upon the 
occurrence of such event, the assets and funds thus distributed among the 
holders of the Series B Preferred Stock shall be insufficient to permit the 
payment to such holders of the full aforesaid preferential amounts, then the 
entire assets and funds of the Corporation legally available for distribution to
the holders of Series B Preferred Stock shall be distributed ratably among the 
holders of the Series B Preferred Stock in proportion to the preferential amount
each such holder is otherwise entitled to receive.

                 (b)  Series A Preferred Stock  In the event of any 
                      ------------------------
liquidation, dissolution or winding up of the Corporation, either voluntary or 
involuntary, after payment in full of the preferential amount of the shares of 
Series B Preferred Stock as set forth above, the holders of Series A Preferred 
Stock shall be entitled to receive, prior and in preference to any distribution
of any of the assets of  the Corporation to the holders of Common Stock by 
reason of their ownership thereof, an amount per share equal to $1.00 (as 
adjusted for stock splits, combinations or similar events) for each outstanding 
share of Series A Preferred Stock plus an amount equal to all dividends declared
but theretofore unpaid. If upon the occurrence of such event, the assets and 
funds thus distributed among the holders of the Series A Preferred Stock shall 
be insufficient to permit the payment to such holders of the full aforesaid 
preferential amounts, then the entire assets and funds of the Corporation 
legally available for distribution to the holders of Series A Preferred Stock 
shall be distributed ratably among the holders of the Series A Preferred Stock
in proportion to the preferential amount each such holder is otherwise entitled 
to receive.

                 (c)  Upon the completion of the distributions required by 
subsections (a) and (b) of this Section 2 of this Article IV  B, the remaining 
assets of the Corporation available for distribution to stockholders shall be 
distributed among the holders of the Series A Preferred Stock and the Common 
Stock pro rata based on the number of shares of Common Stock held by each holder
of Common Stock and issuable upon conversion of all such Series A Preferred 
Stock; provided, however, that the total distribution to the holders of Series A
Preferred Stock pursuant to subsections (b) and (c) of this Section 2 of this 
Article IV B shall not exceed an amount per share equal to $1.50 (not including 
any dividends declared but theretofore unpaid).

                 (d)  For purposes of this Section 2 of this Article IV B, a 
liquidation, dissolution or winding up of the Corporation shall be deemed to be 
occasioned by, or to include, (A) the acquisition of the Corporation by another 
entity by means of any transaction or series of related transactions 
(including, without limitation, any reorganization, merger or consolidation

                                      -4-


<PAGE>
 
but, excluding any merger effected exclusively for the purpose of changing the 
domicile of the Corporation); or (B) a sale of all or substantially all of the 
assets of the Corporation; unless the Corporation's stockholders of record as 
constituted immediately prior to such acquisition or sale will, immediately 
after such acquisition or sale (by virtue of securities issued as consideration 
for the Corporation's acquisition or sale or otherwise), hold at least 50% of 
the voting power of the surviving or acquiring entity.

            3.  Redemption.  Neither the Series A Preferred Stock nor the 
                ---------- 
Series B Preferred Stock is redeemable.

            4.  Conversion.  The holders of the Series A Preferred Stock and 
                ----------
the holders of the Series B Preferred Stock shall have conversion rights as 
follows (the "Conversion Rights"):

                 (a) Rights to Convert. (i) Series A Preferred Stock. Each share
                     -----------------      ------------------------
of Series A Preferred Stock shall be convertible, at the option of the holder 
thereof at any time after the date of issuance of such share at the office of 
the Corporation or any transfer agent for such stock, into such number of 
fully-paid and non-assessable shares of Common Stock as is determined by 
dividing the Original Issue Price by the Conversion Price at the time in effect 
for such shares.  The initial Conversion Price per share for shares of Series A 
Preferred Stock and the Original Issue Price for the Series A Preferred Stock 
shall be $1.00; provided, however, that the Conversion Price for the Series A 
Preferred Stock shall be subject to adjustment as set forth in subsection (d) of
this Section 4 of this Article IV B.

                               (ii)  Series B Preferred Stock.  Each share of 
                                     ------------------------
Series B Preferred Stock shall be convertible, at the option of the holder 
thereof at any time after the date of issuance of such share at the office of 
the Corporation or any transfer agent for such stock, into such number of 
fully-paid and non-assessable shares of Common Stock as is determined by 
dividing the Series B Original Issue Price by the Conversion Price at the time 
in effect for such shares.  The initial Conversion Price per share for shares of
Series B Preferred Stock and the Series B Original Issue Price for the Series B 
Preferred  Stock shall be $1.50; provided, however, that the Conversion Price 
for the Series B Preferred Stock shall be subject to  adjustment as set forth in
subsection (d) of this Section 4 of this Article IV B.

                 (b)  Automatic Conversion.  Each share of Series A Preferred 
                      --------------------
Stock and Series B Preferred Stock shall automatically be converted into such 
number of fully-paid and nonassessable shares of Common Stock as is determined 
by dividing

                                      -5-
<PAGE>
 
the Original Issue Price or Series B Original Issue Price, as applicable, by the
Conversion Price at the time in effect for such shares immediately upon the 
earlier of (i) the closing of the Corporation's sale of its Common Stock in a 
firm commitment, underwritten public offering pursuant to a registration 
statement under the Securities Act of 1933, as amended (the "Act"), the public 
offering price of which is not less than $3.00 per share (subject to adjustment 
for stock splits, combinations or similar events) and which results in gross 
proceeds of not less than $10,000,000 in the aggregate (before deducting 
underwriting commissions and discounts and expenses) or (ii) with respect to the
Series A Preferred Stock, the date specified by written consent or agreement of 
the holders of fifty-one percent (51%) of the then outstanding shares of 
Series A Preferred Stock or (iii) with respect to the Series B Preferred Stock, 
the date specified by written consent or agreement of the holders of fifty-one 
percent (51%) of the then outstanding shares of Series B Preferred Stock.

                 (c)  Mechanics of Conversion.  Before any holder of Series A 
                      -----------------------  
Preferred Stock or Series B Preferred Stock shall be entitled to convert the 
same into shares of Common Stock, such holder shall surrender the certificate or
certificates therefor, duly endorsed, at the office of the Corporation or of any
transfer agent for the Series A Preferred Stock or Series B Preferred Stock, as 
the case may be, and shall give written notice to the Corporation at its 
principal corporate office, of the election to convert the same and shall state 
therein the name or names in which the certificate or certificates for shares of
Common Stock are to be issued. The Corporation shall, as soon as practicable 
thereafter, issue and deliver at such office to such holder of preferred stock, 
or to the nominee or nominees of such holder, a certificate or certificates for 
the number of shares of Common Stock to which such holder shall be entitled as 
aforesaid. Such conversion shall be deemed to have been made immediately prior 
to the close of business on the date of such surrender of the shares of Series A
Preferred Stock or Series B Preferred Stock, as the case may be, to be 
converted, and the person or persons entitled to receive the shares of Common 
Stock issuable upon such conversion shall be treated for all purposes as the 
record holder or holders of such shares of Common Stock as of such date. If the 
conversion is in connection with an underwritten offering of securities 
registered pursuant to the Act, the conversion may, at the option of any holder 
tendering Series A Preferred Stock or Series B Preferred Stock for conversion, 
be conditioned upon the closing with the underwriters of the sale of securities 
pursuant to such offering, in which event the person(s) entitled to receive the 
Common Stock upon conversion of the Series A Preferred Stock or Series B 
Preferred Stock shall not be deemed to have converted such Series A Preferred 
Stock or Series B

                                      -6-



<PAGE>
 

Preferred Stock until immediately prior to the closing of such sale of 
securities.

     Upon the conversion of the Series A Preferred Stock or Series B preferred
Stock pursuant to subsection (b) above, all certificates evidencing the shares
of Series A Preferred Stock or Series B Preferred Stock which are converted in
accordance with the provision thereof shall, from and after the date such shares
are so converted, be deemed to have been retired and cancelled and the shares of
Series A Preferred Stock or Series B Preferred Stock represented thereby
converted into Common Stock for all purposes, regardless of whether the holder
or holders thereof shall have surrendered such certificates on or prior to such
date.


                 (d)  Conversion Price Adjustments of Preferred Stock.  The 
                      -----------------------------------------------
Conversion Price of the Series A Preferred Stock and Series B Preferred 
Stock shall be subject to adjustment from time to time as set forth below.

                     
                      (i) (A)  If the Corporation shall issue, (x) after the 
date upon which any shares of Series A Preferred Stock were first issued (for 
purposes of adjusting the Series A Preferred Stock's Conversion Price) or (y) 
after the date upon which any shares of Series B Preferred Stock were first 
issued (for purposes of adjusting the Series B Preferred Stock's Conversion 
Price) (each being a "Purchase Date" with respect to such series), any 
Additional Stock (as defined below for purposes of this Article IV B) without 
consideration or for a consideration per share less than the Conversion Price 
for such series in effect immediately prior to the issuance of such Additional 
Stock, the Conversion Price for each such series in effect immediately prior to 
each such issuance shall forthwith (except as otherwise provided in this clause 
(i) be adjusted to a price determined by multiplying each such series' 
Conversion Price by a fraction, the numerator of which shall be the number   
of shares of Common Stock outstanding immediately prior to such issuance plus 
the number of shares of Common Stock that the aggregate consideration received 
by the Corporation for such issuance would purchase at such Conversion Price, 
and the denominator of which shall be the number of shares of Common Stock 
outstanding immediately prior to such issuance plus the number of shares of such
Additional Stock.

                          (B)  Except to the limited extent provided for in
subsections (E)(3) and (E)(4) of this Section 4(d) of this Article IV B, no
adjustment of any such Conversion Price pursuant to this subsection 4(d)(i)
shall have the effect of increasing such Conversion Price above the Conversion
Price in effect immediately prior to such adjustment.

                                      -7-

<PAGE>
 
                                       (C)  In the case of the issuance of 
Additional Stock for cash, the consideration shall be deemed to be the amount of
cash paid therefor before deducting any reasonable discounts, commissions or 
other expenses allowed, paid or incurred by the Corporation for any underwriting
or otherwise in connection with the issuance and sale thereof.

                                       (D)  In the case of the issuance of 
Additional Stock for a consideration in whole or in part other than cash, the 
consideration other than cash shall be deemed to be the fair value thereof as 
determined in good faith by the Board of Directors.

                                       (E)  In the case of the issuance (whether
before, on or after a Purchase Date) of options to purchase or rights to 
subscribe for Common Stock, securities by their terms convertible into or 
exchangeable for Common Stock or options to purchase or rights to subscribe for 
such convertible or exchangeable securities, the following provisions shall 
apply for all purposes of this subsection 4(d)(i) and subsection 4(d)(ii):

                                            (1)  The aggregate maximum number of
shares of Common Stock deliverable upon exercise (assuming the satisfaction of 
any conditions to exercisability, including without limitation, the passage of 
time, but without taking into account potential anti-dilution adjustments) of 
such options to purchase or rights to subscribe for Common Stock shall be deemed
to have been issued at the time such options or rights were issued and for a 
consideration equal to the consideration (determined in the manner provided in 
subsections 4(d)(i)(C) and 4(d)(i)(O) of this Article IV B), if any, received by
the Corporation upon the issuance of such options or rights plus the minimum 
exercise price provided in such options or rights (without taking into account
potential anti-dilution adjustments) for the Common Stock covered thereby.

                                            (2)  The aggregate maximum number of
shares of Common Stock deliverable upon conversion of or in exchange (assuming 
the satisfaction of any conditions to convertibility or exchangeability, 
including, without limitation, the passage of time, but without taking into 
account potential anti-dilution adjustments) for any such convertible or 
exchangeable securities or upon the exercise of options to purchase or rights to
subscribe for such convertible or exchangeable securities and subsequent 
conversion or exchange thereof, shall be deemed to have been issued at the time 
such securities were issued or such options or rights were issued and for a 
consideration equal to the consideration, if any, received by the Corporation 
for any such securities and related options or rights (excluding any cash 
received on account of accrued 

                                      -8-
<PAGE>
 
interest or accrued dividends), plus the minimum additional consideration, if 
any, to be received by the Corporation (without taking into account potential 
anti-dilution adjustments) upon the conversion or exchange of such securities or
the exercise of any related options or rights (the consideration in each case to
be determined in the manner provided in subsections 4(d)(i)(C) and (d)(i)(D)) of
this Article IV B.

                                            (3)  In the event of any change in 
the number of shares of Common Stock deliverable or in the consideration payable
to the Corporation upon exercise of such options or rights or upon conversion of
or in exchange for such convertible or exchangeable securities, (excluding a 
change resulting solely from the anti-dilution provisions thereof if such change
results from an event which gives rise to an anti-dilution adjustment under this
subsection 4(d)), the Conversion Price of the Series A Preferred Stock and of 
the Series B Preferred Stock, to the extent in any way affected by or computed 
using such options, rights or securities, shall be recomputed to reflect such 
change, but no further adjustment shall be made for the actual issuance of 
Common Stock or any payment of such consideration upon the exercise of any such 
options or rights or the conversion or exchange of such securities.

                                            (4)  Upon the expiration of any such
options or rights, the termination of any such rights to convert or exchange or 
the expiration of any options or rights related to such convertible or 
exchangeable securities, the Conversion Price of the Series A Preferred Stock 
and of the Series B Preferred Stock, to the extent in any way affected by or 
computed using such options, rights or securities or options or rights related 
to such securities, shall be recomputed to reflect the issuance of only the 
number of shares of Common Stock (and convertible or exchangeable securities 
which remain in effect) actually issued upon the exercise of such options or 
rights, upon the conversion or exchange of such securities or upon the exercise 
of the options or rights related to such securities.

                                            (5)  The number of shares of Common 
Stock deemed issued and the consideration deemed paid therefor pursuant to 
subsections 4(d)(i)(E)(1) and (2) of Article IV B shall be appropriately 
adjusted to reflect any change, termination or expiration of the type described 
in either subsection 4(d)(i)(E)(3) or (4) of Article IV B.

                                  (ii)  "Additional Stock" shall mean, for each 
of the Series A Preferred Stock and Series B Preferred Stock, any shares of 
common Stock issued (or deemed to have been issued pursuant to subsection 4(d)
(i)(E) of Article IV B) by the Corporation after the respective Purchase Date 
other than:

                                      -9-
<PAGE>
 
                                      (A)  Common Stock issued pursuant to a 
transaction described in subsection 4(d)(iii) of Article IV B hereof;

                                      (B)  Common Stock issuable or issued to
employees, advisors, consultants or outside directors of the Corporation,
without consideration or for a consideration per share less than the Conversion
Price for the Series A Preferred Stock or Series B Preferred Stock, as the case
may be, in effect immediately prior to the time such Common Stock is issued,
directly or pursuant to a stock option plan or restricted stock plan approved by
the Board of Directors of the Corporation; provided, however, that the
cumulative total number of shares of Common Stock so issuable and issued (and
not repurchased at cost by the Corporation in connection with the termination of
employment) does not exceed at any time 3,377,326 shares of Common Stock
(subject to adjustment for stock splits, combinations or similar events;

                                      (C)  Common Stock issued or issuable 
upon conversion of the Series A Preferred Stock or Series B Preferred Stock; or

                                      (D)  Common Stock issuable or issued upon
exercise of certain warrants issued or issuable to KBL Healthcare, Inc. (or its
designees) and Dr. Richard J. Cohen; provided, however, that the cumulative
total number of shares of Common Stock so issuable or issued does not exceed
877,077 shares of Common Stock (before giving effect to any anti-dilution
adjustments provided for therein) .

                                 (iii)  In the event the Corporation should at
any time or from time to time after a Purchase Date fix a record date for the
effectuation of a split or subdivision of the outstanding shares of Common Stock
or the determination of holders of Common Stock entitled to receive a dividend
or other distribution payable in additional shares of Common Stock or other
securities or rights convertible into, or entitling the holder thereof to
receive directly or indirectly, additional shares of Common Stock (hereinafter
referred to as "Common Stock Equivalents") without payment of any consideration
by such holder for the additional shares of Common Stock or the Common Stock
Equivalents (including the additional shares of Common Stock issuable upon
conversion or exercise thereof), then, as of such record date (or the date of
such dividend distribution, split or subdivision if no record date is fixed),
the Conversion Price of the Series A Preferred Stock and of the Series B
Preferred Stock shall be appropriately decreased so that the number of shares of
Common Stock issuable on conversion of each share of such Series A Preferred
Stock or Series B Preferred Stock, as the case may be, shall be increased in
proportion to such increase in the

                                     -10-











<PAGE>
 
aggregate of shares of Common Stock outstanding and those issuable with respect 
to such Common Stock Equivalents.

                                    (iv)  If the number of shares of Common
Stock outstanding at any time after a Purchase Date is decreased by a
combination of the outstanding shares of Common Stock, then, following the
record date of such combination, the Conversion Price for the Series A Preferred
Stock and for the Series B Preferred Stock, as the case may be, shall be
appropriately increased so that the number of shares of Common Stock issuable on
conversion of each share of such series shall be decreased in proportion to such
decrease in outstanding shares.

                              (e)  Other Distribution. In the event the
                                   ------------------
Corporation shall declare a distribution payable in securities of other persons,
evidences of indebtedness issued by the Corporation or other persons, assets
(excluding cash dividends) or options or rights not referred to in subsection
4(d)(i) of this Article IV B, then, in each such case for the purpose of this
subsection 4(e), the holders of the Series A Preferred Stock and of the Series B
Preferred Stock shall be entitled to a proportionate share of any such
distribution as though they were the holders of the number of shares of Common
Stock of the Corporation into which their shares of Series A Preferred Stock and
Series B Preferred Stock are convertible as of the record date fixed for the
determination of the holders of Common Stock of the Corporation entitled to
receive such distribution.

                              (f)  Recapitalizations. If at any time or from
                                   -----------------
time to time there shall be a recapitalization of the Common Stock (other than a
subdivision, combination or merger or sale of assets transaction provided for
elsewhere in this Section 4 or Section 2) provision shall be made so that the
holders of the Series A Preferred Stock and Series B Preferred Stock shall
thereafter be entitled to receive upon conversion of the Series A Preferred
Stock or Series B Preferred Stock the number of shares of stock or other
securities or property of the Corporation or otherwise, to which a holder of
Common Stock deliverable upon conversion would have been entitled on such
recapitalization. In any such case, appropriate adjustment shall be made in the
application of the provisions of this Section 4 with respect to the rights of
the holders of the Series A Preferred Stock and Series B Preferred Stock after
the recapitalization to the end that the provisions of this Section 4 (including
adjustment of the Conversion Price then in effect and the number of shares
issuable upon conversion) shall be applicable after that event as nearly
equivalent as may be practicable.

                              (g)  No Impairment. The Corporation will not, by
                                   -------------
amendment of its Amended and Restated Certificate of Incorporation or through

observance or performance of any of the terms to be observed or performed 
hereunder by the Corporation, but will at all times in good faith assist in the 
carrying out of all the provisions of this Section 4 and in the taking of all 
such action as may be necessary or appropriate in order to protect the 
Conversion Rights of the holders of the Series A Preferred Stock and Series B 
Preferred Stock against impairment.

                       (h)  No Fractional Shares and Certificate as to

                             (i)  No fractional shares shall be issued upon the
conversion of any share or shares of the Series A Preferred Stock or Series B
Preferred Stock, and the number of shares of Common Stock to be issued shall be
rounded to the nearest whole share. Whether or not fractional shares are
issuable upon such conversion shall be determined on the basis of the total
number of shares of Series A Preferred Stock or Series B Preferred Stock the
holder is at the time converting into Common Stock and the number of shares of
Common Stock issuable upon such aggregate conversion.

                            (ii) Upon the occurrence of each adjustment or
readjustment of the Conversion Price of Series A Preferred Stock or Series B
Preferred Stock pursuant to this Section 4, the Corporation, at its expense,
shall promptly compute such adjustment or readjustment in accordance with the
terms hereof and prepare and furnish to each holder of Series A Preferred Stock
or Series B Preferred Stock, as the case may be, a certificate setting forth
such adjustment or readjustment and showing in reasonable detail the facts upon
which such adjustment or readjustment is based. The Corporation shall, upon the
written request at any time of any holder of Series A Preferred Stock or Series
B Preferred Stock, furnish or cause to be furnished to such holder a like
certificate setting forth (A) such adjustment and readjustment, (B) the
Conversion Price for such Series A Preferred Stock or Series B Preferred Stock
at the time in effect, and (C) the number of shares of Common Stock and the
amount, if any, of other property which at the time would be received upon the
conversion of a share of Series A Preferred Stock or Series B Preferred Stock.

                       (i)  Notices of Record Date. In the event of any taking
by the Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, the Corporation
shall mail to each holder of Series A Preferred Stock and Series B Preferred
Stock, at least twenty (20) days

prior to the date specified therein, a notice specifying the date on which any 
such record is to be taken for the purpose of such dividend, distribution or 
right, and the amount and character of such dividend, distribution or right.

                 (j)  Reservation of Stock Issuable Upon Conversion.  The 
                      ---------------------------------------------  
Corporation shall at all times reserve and keep available out of its authorized 
but unissued shares of Common Stock, solely for the purpose of effecting the 
conversion of the shares of the Series A Preferred Stock and Series B Preferred 
Stock, such number of its shares of Common Stock as shall from time to time be 
sufficient to effect the conversion of all outstanding shares of the Series A 
Preferred Stock and Series B Preferred Stock; and if at any time the number of 
authorized but unissued shares of Common Stock shall not be sufficient to effect
the conversion of all then outstanding shares of the Series A Preferred Stock 
and Series B Preferred Stock, in addition to such other remedies as shall be 
available to the holder of such Preferred Stock, the Corporation will take such 
corporate action as may, in the opinion of its counsel, be necessary to increase
its authorized but unissued shares of Common Stock to such number of shares as 
shall be sufficient for such purposes, including, without limitation, engaging 
in best efforts to obtain the requisite stockholder approval of any necessary 
amendment to these provisions.

                 (k)  Notices.  Any notice required by the provisions of this 
                      -------
Section 4 to be given to the holders of shares of Series A Preferred Stock and 
Series B Preferred Stock shall be deemed given on the date it is sent if 
deposited in the United States mail, postage prepaid, and addressed to each 
holder of record at his, her or its address appearing on the books of the 
Corporation.

             5.  Voting Rights.  (a)  General.  In addition to the special

voting rights set forth below, the holders of each share of Series A Preferred 
Stock and Series B Preferred Stock shall have the right to one vote for each 
share of Common Stock into which such Series A Preferred Stock or Series B 
Preferred Stock could then be converted, and with respect to such vote, such 
holder shall have full voting rights and powers equal to the voting rights and 
powers of the holders of Common Stock, and shall be entitled, notwithstanding 
any provision hereof, to notice of any stockholders' meeting in accordance with
the bylaws of the Corporation, and shall be entitled to vote, together with
holders of Common Stock, with respect to any question upon which holders of
Common Stock have the right to vote. Unless otherwise provided herein or
provided by applicable law, where entitled to vote, the holders of Common Stock,
Series A Preferred Stock and Series B Preferred Stock shall vote together as a
singe class. Fractional votes shall not, however, be permitted and any
fractional voting rights available on an as-converted basis

Series B Preferred Stock held by each holder could be converted) shall be 
rounded to the nearest whole number (with one-half being rounded upward).

                    (b)  Series B Director.  So long as at least 25% of the 
                         -----------------
originally issued Series B Preferred Stock remains outstanding, the holders of 
the Series B Preferred Stock, voting together as a class, shall be entitled to 
elect one director to the Board of Directors of the Corporation (the "Series B 
Director").  Should a vacancy occur with respect to the Series B Director, 
whether arising through death, resignation or removal, such vacancy shall be 
filled by the holders of the Series B Preferred Stock.

                    (c)  Special Class Vote.  Holders of the Series B Preferred 
                         ------------------
Stock shall vote separately as a class on (i) all matters involving the sale by 
the Corporation of all or substantially all of its assets or a merger or 
consolidation involving the Corporation after which the Corporation's 
stockholders of record as constituted immediately prior to the consummation of 
such transaction would hold, immediately after consummation of such transaction,
securities constituting less than fifty percent (50%) of the voting power of the
surviving or resulting entity unless the consideration to be received by the 
holders of Series B Preferred Stock as a result of such transaction would be at 
least $3.00 per share of Series B Preferred Stock and (ii) any amendment to the 
Company's Amended and Restated Certificate of Incorporation that adversely 
affects the Series B Preferred Stock in a manner differently and adversely from 
other shares of Preferred Stock or Common Stock.  However, except as otherwise 
set forth below, in all cases where the Series A Preferred Stock is similarly 
adversely affected, the holders of Series A Preferred Stock and Series B 
Preferred Stock shall vote together as a class.

          Holders of the Series A Preferred Stock and holders of the Series B 
Preferred Stock shall vote together as a class (i) on any amendment to the 
Company's Amended and Restated Certificate of Incorporation that authorizes any 
equity security, including any other security or debt instrument convertible 
into or exercisable for any such equity security, having a preference over the 
Series A Preferred Stock, but not over the Series B Preferred Stock, with 
respect to dividends, redemption or liquidation, or (ii) to authorize the 
Company to declare, or pay, any cash dividends on any Common Stock or Preferred 
Stock of the Company.  Notwithstanding the foregoing, holders of the Series A 
Preferred Stock and holders the Series B Preferred Stock shall each vote as a 
separate class on any amendment to the Company's Amendment and Restated 
Certificate of Incorporation that authorizes any equity security, including any 
other security or debt instrument convertible into or exercisable for any such 
equity

              -------------------------
Preferred Stock or Series B Preferred Stock shall be converted pursuant to 
Section 4 of Article IV B, the shares so converted shall be cancelled and shall 
not be issuable by the Corporation.  The Amended and Restated Certificate of 
Incorporation of the Corporation may be appropriately amended from time to time 
to effect the corresponding reduction in the Corporation's authorized capital 
stock.

         written actions in lieu of meetings).  There shall be no
         cumulative voting.

              The number of authorized shares of Common Stock may be
         increased or decreased (but not below the number of shares thereof
         then outstanding) by the affirmative vote of the holders of a
         majority of the stock of the Corporation entitled to vote,
         irrespective of the provisions of Section 242(b)(2) of the General
         Corporation Law of Delaware.

              3.   Dividends.  Dividends may be declared and paid on the
                   ---------
         Common Stock from funds lawfully available therefor as and when
         determined by the Board of Directors and subject to any
         preferential dividend rights of any then outstanding Preferred
         Stock.

              4.   Liquidation.  Upon the dissolution or liquidation of the
                   -----------
         Corporation, whether voluntary or involuntary, holders of Common
         Stock will be entitled to receive all assets of the Corporation
         available for distribution to its stockholders, subject to any
         preferential rights of any then outstanding Preferred Stock.

         B.   PREFERRED STOCK. 
              --------------- 

              Preferred Stock may be issued from time to time in one or
         more series, each of such series to have such terms as stated or
         expressed herein and in the resolution or resolutions providing
         for the issue of such series adopted by the Board of Directors of
         the Corporation as hereinafter provided.  Any shares of Preferred



                                        - 2 -
<PAGE>
 
         Stock which may be redeemed, purchased or acquired by the
         Corporation may be reissued except as otherwise provided by law or
         this Certificate of Incorporation.  Different series of Preferred
         Stock shall not be construed to constitute different classes of
         shares for the purposes of voting by classes unless expressly
         provided.  

              Authority is hereby expressly granted to the Board of
         Directors from time to time to issue the Preferred Stock in one or
         more series, and in connection with the creation of any such
         series, by resolution or resolutions providing for the issue of
         the shares thereof, to determine and fix such voting powers, full
         or limited, or no voting powers, and such designations,
         preferences and relative participating, optional or other special
         rights, and qualifications, limitations or restrictions thereof,
         including without limitation thereof, dividend rights, conversion
         rights, redemption privileges and liquidation preferences, as
         shall be stated and expressed in such resolutions, all to the full
         extent now or hereafter permitted by the General Corporation Law
         of Delaware.  Without limiting the generality of the foregoing,
         the resolutions providing for issuance of any series of Preferred
         Stock may provide that such series shall be superior or rank
         equally or be junior to the Preferred Stock of any other series to
         the extent permitted by law and this Certificate of Incorporation.
         Except as otherwise provided in this Certificate of Incorporation,
         no vote of the holders of the Preferred Stock or Common Stock
         shall be a prerequisite to the designation or issuance of any
         shares of any series of the Preferred Stock authorized by and
         complying with the conditions of this Certificate of
         Incorporation, the right to have such vote being expressly waived
         by all present and future holders of the capital stock of the
         Corporation.

              FIFTH.    The Corporation shall have a perpetual existence.  

              SIXTH.    In furtherance of and not in limitation of powers
         conferred by statute, it is further provided:

                   1.   Election of directors need not be by written
         ballot.

                   2.   The Board of Directors is expressly authorized to
         adopt, amend or repeal the By-Laws of the Corporation.

              SEVENTH.  Whenever a compromise or arrangement is proposed
         between this Corporation and its creditors or any class of them
         and/or between this Corporation and its stockholders or any class
         of them, any court of equitable jurisdiction within the State of
         Delaware may, on the application in a summary way of this
         Corporation or of any creditor or stockholder thereof, or on the



                                        - 3 -
<PAGE>
 
         application of any receiver or receivers appointed for this
         Corporation under the provisions of section 291 of Title 8 of the
         Delaware Code or on the application of trustees in dissolution or
         of any receiver or receivers appointed for this Corporation under
         the provisions of section 279 of Title 8 of the Delaware Code
         order a meeting of the creditors or class of creditors, and/or of
         the stockholders or class of stockholders of this Corporation, as
         the case may be, to be summoned in such manner as the said court
         directs.  If a majority in number representing three-fourths in
         value of the creditors or class of creditors, and/or of the
         stockholders or class of stockholders of this Corporation, as the
         case may be, agree to any compromise or arrangement and to any
         reorganization of this corporation as a consequence of such
         compromise or arrangement, the said compromise or arrangement and
         the said reorganization shall, if sanctioned by the court to which
         the said application has been made, be binding on all the
         creditors or class of creditors, and/or on all the stockholders or
         class of stockholders, of this Corporation, as the case may be,
         and also on this Corporation.

              EIGHTH.   Except to the extent that the General Corporation
         Law of the State of Delaware prohibits the elimination or
         limitation of liability of directors for breaches of fiduciary
         duty, no director of the Corporation shall be personally liable to
         the Corporation or its stockholders for monetary damages for any
         breach of fiduciary duty as a director, notwithstanding any
         provision of law imposing such liability.  No amendment to or
         repeal of this provision shall apply to or have any effect on the
         liability or alleged liability of any director of the Corporation
         for or with respect to any acts or omissions of such director
         occurring prior to such amendment.

              NINTH.  1.     Action, Suits and Proceedings Other than by or
                             ----------------------------------------------
         in the Right of the Corporation.  The Corporation shall indemnify
         -------------------------------  
         each person who was or is a party or is threatened to be made a
         party to any threatened, pending or completed action, suit or
         proceeding, whether civil, criminal, administrative or
         investigative (other than an action by or in the right of the
         Corporation), by reason of the fact that he is or was, or has
         agreed to become, a director or officer of the Corporation, or is
         or was serving, or has agreed to serve, at the request of the
         Corporation, as a director, officer or trustee of, or in a similar
         capacity with, another corporation, partnership, joint venture,
         trust or other enterprise (including any employee benefit plan)
         (all such persons being referred to hereafter as an "Indemnitee"),
         or by reason of any action alleged to have been taken or omitted
         in such capacity, against all expenses (including attorneys' fees)
         judgment, fines and amounts paid in settlement actually and
         reasonably incurred by him or on his behalf in connection with
         such action, suit or proceeding and any appeal therefrom, if he



                                        - 4 -
<PAGE>
 
         acted in good faith and in a manner he reasonably believed to be
         in, or not opposed to, the best interests of the Corporation, and,
         with respect to any criminal action or proceeding, had no
         reasonable cause to believe his conduct was unlawful.  The
         termination of any action, suit or proceeding by judgment, order,
         settlement, conviction or upon a plea of nolo contendere or its
                                                  ---- ---------- 
         equivalent, shall not, of itself, create a presumption that the
         person did not act in good faith and in a manner which he
         reasonably believed to be in, or not opposed to, the best
         interests of the Corporation, and, with respect to any criminal
         action or proceeding, had reasonable cause to believe that his
         conduct was unlawful.  Notwithstanding anything to the contrary in
         this Article, except as set forth in Section 6 below, the
         Corporation shall not indemnify an Indemnitee seeking
         indemnification in connection with a proceeding (or part thereof)
         initiated by the Indemnitee unless the initiation thereof was
         approved by the Board of Directors of the Corporation.

              2.   Actions or Suits by or in the Right of the Corporation.
                   ------------------------------------------------------
         The Corporation shall indemnify any Indemnitee who was or is a
         party or is threatened to be made a party to any threatened,
         pending or completed action or suit by or in the right of the
         Corporation to procure a judgment in its favor by reason of the
         fact that he is or was, or has agreed to become, a director or
         officer of the Corporation, or is or was serving, or has agreed to
         serve, at the request of the Corporation, as a director, officer
         or trustee of, or in a similar capacity with, another corporation,
         partnership, joint venture, trust or other enterprise (including
         any employee benefit plan), or by reason of any action alleged to
         have been taken or omitted in such capacity, against all expenses
         (including attorneys' fees) and amounts paid in settlement
         actually and reasonably incurred by him or on his behalf in
         connection with such action, suit or proceeding and any appeal
         therefrom, if he acted in good faith and in a manner he reasonably
         believed to be in, or not opposed to, the best interests of the
         Corporation, except that no indemnification shall be made in
         respect of any claim, issue or matter as to which such person
         shall have been adjudged to be liable to the Corporation unless
         and only to the extent that the Court of Chancery of Delaware or
         the court in which such action or suit was brought shall determine
         upon application that, despite the adjudication of such liability
         but in view of all the circumstances of the case, such person is
         fairly and reasonably entitled to indemnity for such expenses
         (including attorneys' fees) which the Court of Chancery of
         Delaware or such other court shall deem proper.

              3.   Indemnification for Expenses of Successful Party.
                   ------------------------------------------------
         Notwithstanding the other provisions of this Article, to the
         extent that an Indemnitee has been successful, on the merits or
         otherwise, in defense of any action, suit or proceeding referred



                                        - 5 -
<PAGE>
 
         to in Sections 1 and 2 of this Article, or in defense of any
         claim, issue or matter therein, or on appeal from any such action,
         suit or proceeding, he shall be indemnified against all expenses
         (including attorneys' fees) actually and reasonably incurred by
         him or on his behalf in connection therewith.  Without limiting
         the foregoing, if any action, suit or proceeding is disposed of,
         on the merits or otherwise (including a disposition without
         prejudice), without (i) the disposition being adverse to the
         Indemnitee, (ii) an adjudication that the Indemnitee was liable to
         the Corporation, (iii) a plea of guilty or nolo contendere by the
                                                    ---- ----------
         Indemnitee, (iv) an adjudication that the Indemnitee did not act
         in good faith and in a manner he reasonably believed to be in or
         not opposed to the best interests of the Corporation, and (v) with
         respect to any criminal proceeding, an adjudication that the
         Indemnitee had reasonable cause to believe his conduct was
         unlawful, the Indemnitee shall be considered for the purposes
         hereof to have been wholly successful with respect thereto.

              4.   Notification and Defense of Claim.  As a condition
                   ---------------------------------
         precedent to his right to be indemnified, the Indemnitee must
         notify the Corporation in writing as soon as practicable of any
         action, suit, proceeding or investigation involving him for which
         indemnity will or could be sought.  With respect to any action,
         suit, proceeding or investigation of which the Corporation is so
         notified, the Corporation will be entitled to participate therein
         at its own expense and/or to assume the defense thereof at its own
         expense, with legal counsel reasonably acceptable to the
         Indemnitee.  After notice from the Corporation to the Indemnitee
         of its election so to assume such defense, the Corporation shall
         not be liable to the Indemnitee for any legal or other expenses
         subsequently incurred by the Indemnitee in connection with such
         claim, other than as provided below in this Section 4.  The
         Indemnitee shall have the right to employ his own counsel in
         connection with such claim, but the fees and expenses of such
         counsel incurred after notice from the Corporation of its
         assumption of the defense thereof shall be at the expense of the
         Indemnitee unless (i) the employment of counsel by the Indemnitee
         has been authorized by the Corporation, (ii) counsel to the
         Indemnitee shall have reasonably concluded that there may be a
         conflict of interest or position on any significant issue between
         the Corporation and the Indemnitee in the conduct of the defense
         of such action or (iii) the Corporation shall not in fact have
         employed counsel to assume the defense of such action, in each of
         which cases the fees and expenses of counsel for the Indemnitee
         shall be at the expense of the Corporation, except as otherwise
         expressly provided by this Article.  The Corporation shall not be
         entitled, without the consent of the Indemnitee, to assume the
         defense of any claim brought by or in the right of the Corporation
         or as to which counsel for the Indemnitee shall have reasonably
         made the conclusion provided for in clause (ii) above.

              5.   Advance of Expenses.  Subject to the provisions of
                   -------------------
         Section 6 below, in the event that the Corporation does not assume
         the defense pursuant to Section 4 of this Article of any action,
         suit, proceeding or investigation of which the Corporation
         receives notice under this Article, any expenses (including
         attorneys' fees) incurred by an Indemnitee in defending a civil or
         criminal action, suit, proceeding or investigation or any appeal
         therefrom shall be paid by the Corporation in advance of the final
         disposition of such matter; provided, however, that the payment of
                                     --------  -------
         such expense incurred by an Indemnitee in advance of the final
         disposition of such matter shall be made only upon receipt of an
         undertaking by or on behalf of the Indemnitee to repay all amounts
         so advanced in the event that it shall ultimately be determined
         that the Indemnitee is not entitled to be indemnified by the
         Corporation as authorized in this Article.  Such undertaking may
         be accepted without reference to the financial ability of the
         Indemnitee to make such repayment.

              6.   Procedure for Indemnification.  In order to obtain
                   -----------------------------
         indemnification or advancement of expenses pursuant to Section 1,
         2, 3 or 5 of this Article, the Indemnitee shall submit to the
         Corporation a written request, including in such request such
         documentation and information as is reasonably available to the
         Indemnitee and is reasonably necessary to determine whether and to
         what extent the Indemnitee is entitled to indemnification or
         advancement of expenses.  Any such indemnification or advancement
         of expenses shall be made promptly, and in any event within 60
         days after receipt by the Corporation of the written request of
         the Indemnitee, unless with respect to requests under Section 1, 2
         or 5 the Corporation determines, by clear and convincing evidence,
         within such 60-day period that the Indemnitee did not meet the
         applicable standard of conduct set forth in Section 1 or 2, as the
         case may be.  Such determination shall be made in each instance by
         (a) a majority vote of a quorum of the directors of the
         Corporation consisting of persons who are not at that time parties
         to the action, suit or proceeding in question ("disinterested
         directors"), (b) if no such quorum is obtainable, a majority vote
         of a committee of two or more disinterested directors, (c) a
         majority vote of a quorum of the outstanding shares of stock of
         all classes entitled to vote for directors, voting as a single
         class, which quorum shall consist of stockholders who are not at
         that time parties to the action, suit or proceeding in question,
         (c) independent legal counsel (who may be regular legal counsel to
         the Corporation), or (d) a court of competent jurisdiction.

              7.   Remedies.  The right to indemnification or advances as
                   --------
         granted by this Article shall be enforceable by the Indemnitee in
         any court of competent jurisdiction if the Corporation denies such
         request, in whole or in part, or if no disposition thereof is made
         within the 60-day period referred to above in Section 6.  Unless



                                        - 7 -
<PAGE>
 
         otherwise provided by law, the burden of proving that the
         Indemnitee is not entitled to indemnification or advance of
         expenses under this Article shall be on the Corporation.  Neither
         the failure of the Corporation to have made a determination prior
         to the commencement of such action that indemnification is proper
         in the circumstances because the Indemnitee has met the applicable
         standard of conduct, nor an actual determination by the
         Corporation pursuant to Section 6 that the Indemnitee has not met
         such applicable standard of conduct, shall be a defense to the
         action or create a presumption that the Indemnitee has not met the
         applicable standard of conduct.  The Indemnitee's expenses
         (including attorneys' fees) incurred in connection with
         successfully establishing his right to indemnification, in whole
         or in part, in any such proceeding shall also be indemnified by
         the Corporation.

              8.   Subsequent Amendment.  No amendment, termination or
                   -------------------- 
         repeal of this Article or of the relevant provisions of the
         General Corporation Law of Delaware or any other applicable laws
         shall affect or diminish in any way the rights of any Indemnitee
         to indemnification under the provisions hereof with respect to any
         action, suit, proceeding or investigation arising out of or
         relating to any actions, transactions or facts occurring prior to
         the final adoption of such amendment, termination or repeal.

              9.   Other Rights.  The indemnification and advancement of
                   ------------ 
         expenses provided by this Article shall not be deemed exclusive of
         any other rights to which an Indemnitee seeking indemnification or
         advancement of expenses may be entitled under any law (common or
         statutory), agreement or vote of stockholders or disinterested
         directors or otherwise, both as to action in his official capacity
         and as to action in any other capacity while holding office for
         the Corporation, and shall continue as to an Indemnitee who has
         ceased to be a director or officer, and shall inure to the benefit
         of the estate, heirs, executors and administrators of the
         Indemnitee.  Nothing contained in this Article shall be deemed to
         prohibit, and the Corporation is specifically authorized to enter
         into, agreements with officers and directors providing
         indemnification rights and procedures different from those set
         forth in this Article.  In addition, the Corporation may, to the
         extent authorized from time to time by its Board of Directors,
         grant indemnification rights to other employees or agents of the
         Corporation or other persons serving the Corporation and such
         rights may be equivalent to, or greater or less than, those set
         forth in this Article.

              10.  Partial Indemnification.  If an Indemnitee is entitled
                   -----------------------
         under any provision of this Article to indemnification by the
         Corporation for some or a portion of the expenses (including
         attorneys' fees), judgments, fines or amounts paid in settlement



                                        - 8 -
<PAGE>
 
         actually and reasonably incurred by him or on his behalf in
         connection with any action, suit, proceeding or investigation and
         any appeal, therefrom but not, however, for the total amount
         thereof, the Corporation shall nevertheless indemnify the
         Indemnitee for the portion of such expenses (including attorneys'
         fees), judgments, fines or amounts paid in settlement to which the
         Indemnitee is entitled.

              11.  Insurance.  The Corporation may purchase and maintain
                   ---------
         insurance, at its expense, to protect itself and any director,
         officer, employee or agent of the Corporation or another
         corporation, partnership, joint venture, trust or other enterprise
         (including any employee benefit plan) against any expense,
         liability or loss incurred by him in any such capacity, or arising
         out of his status as such, whether or not the Corporation would
         have the power to indemnify such person against such expense,

              TENTH.  The Corporation reserves the right to amend, alter,
         change or repeal any provision contained in this Amended and
         Restated Certificate of Incorporation, in the manner now or
         hereafter prescribed by statute and this Amended and Restated
         Certificate of Incorporation, and all rights conferred upon
         stockholders herein are granted subject to this reservation.

              ELEVENTH.  This Article is inserted for the management of the
         business and for the conduct of the affairs of the Corporation.

              1.   Number of Directors.  The number of directors of the
                   -------------------
         Corporation shall not be less than three.  The exact number of
         directors within the limitations specified in the preceding
         sentence shall be fixed from time to time by, or in the manner
         provided in, the Corporation's By-Laws.

              2.   Classes of Directors.  The Board of Directors shall be
                   -------------------- 
         and is divided into three classes:  Class I, Class II and Class
         III.  No one class shall have more than one director more than any
         other class.  If a fraction is contained in the quotient arrived
         at by dividing the designated number of directors by three, then,
         if such fraction is one-third, the extra director shall be a
         member of Class I, and if such fraction is two-thirds, one of the
         extra directors shall be a member of Class I and one of the extra
         directors shall be a member of Class II, unless otherwise provided
         from time to time by resolution adopted by the Board of Directors.

              3.   Election of Directors.  Elections of directors need not
                   ---------------------
         be by written ballot except as and to the extent provided in the
         By-Laws of the Corporation.

              4.   Terms of Office.  Each director shall serve for a term
                   ---------------
         ending on the date of the third annual meeting following the
         annual meeting at which such director was elected; provided, that
                                                            --------
         each initial director in Class I shall serve for a term ending on
         the date of the annual meeting in 1997; each initial director in
         Class II shall serve for a term ending on the date of the annual
         meeting in 1998; and each initial director in Class III shall
         serve for a term ending on the date of the annual meeting in 1999;
         and provided further, that the term of each director shall be
             -------- -------
         subject to the election and qualification of his successor and to
         his earlier death, resignation or removal.

              5.   Allocation of Directors Among Classes in the Event of
                   -----------------------------------------------------  
         Increases or Decreases in the Number of Directors.  In the event
         -------------------------------------------------   
         of any increase or decrease in the authorized number of directors,
         (i) each director then serving as such shall nevertheless continue
         as a director of the class of which he is a member and (ii) the
         newly created or eliminated directorships resulting from such
         increase or decrease shall be apportioned by the Board of



                                       - 10 -
<PAGE>
 
         Directors among the three classes of directors so as to ensure
         that no one class has more than one director more than any other
         class.  To the extent possible, consistent with the foregoing
         rule, any newly created directorships shall be added to those
         classes whose terms of office are to expire at the latest dates
         following such allocation, and any newly eliminated directorships
         shall be subtracted from those classes whose terms of offices are
         to expire at the earliest dates following such allocation, unless
         otherwise provided from time to time by resolution adopted by the
         Board of Directors.

              6.   Quorum; Action at Meeting.  A majority of the directors
                   -------------------------
         at any time in office shall constitute a quorum for the
         transaction of business.  In the event one or more of the
         directors shall be disqualified to vote at any meeting, then the
         required quorum shall be reduced by one for each director so
         disqualified, provided that in no case shall less than one-third
         of the number of directors fixed pursuant to Section 1 above
         constitute a quorum.  If at any meeting of the Board of Directors
         there shall be less than such a quorum, a majority of those
         present may adjourn the meeting from time to time.  Every act or
         decision done or made by a majority of the directors present at a
         meeting duly held at which a quorum is present shall be regarded
         as the act of the Board of Directors unless a greater number is
         required by law, by the By-Laws of the Corporation or by this
         Amended and Restated Certificate of Incorporation.

              7.   Removal.  Directors of the Corporation may be removed
                   -------
         only for cause by the affirmative vote of the holders of at least
         two-thirds of the shares of the capital stock of the Corporation
         issued and outstanding and entitled to vote.

              8.   Vacancies.  Any vacancy in the Board of Directors,
                   ---------
         however occurring, including a vacancy resulting from an
         enlargement of the board, shall be filled only by a vote of a
         majority of the directors then in office, although less than a
         quorum, or by a sole remaining director.  A director elected to
         fill a vacancy shall be elected to hold office until the next
         election of the class for which such director shall have been
         chosen, subject to the election and qualification of his successor
         and to his earlier death, resignation or removal.

              9.   Stockholder Nominations and Introduction of Business,
                   ----------------------------------------------------
         Etc.  Advance notice of stockholder nominations for election of
         ---
         directors and other business to be brought by stockholders before
         a meeting of stockholders shall be given in the manner provided by
         the By-Laws of the Corporation.

              10.  Amendments to Article.  Notwithstanding any other
                   ---------------------
         provisions of law, this Amended and Restated Certificate of



                                       - 11 -

         Incorporation or the By-Laws of the Corporation, each as amended,
         and notwithstanding the fact that a lesser percentage may be
         specified by law, the affirmative vote of the holders of at least
         seventy-five percent (75%) of the shares of capital stock of the
         Corporation issued and outstanding and entitled to vote shall be
         required to amend or repeal, or to adopt any provision
         inconsistent with, this Article ELEVENTH.

              TWELFTH.  Stockholders of the Corporation may not take any
         action by written consent in lieu of a meeting.  Notwithstanding
         any other provisions of law, the Amended and Restated Certificate
         of Incorporation or the By-Laws of the Corporation, each as
         amended, and notwithstanding the fact that a lesser percentage may
         be specified by law, the affirmative vote of the holders of at
         least seventy-five percent (75%) of the shares of capital stock of
         the Corporation issued and outstanding and entitled to vote shall
         be required to amend or repeal, or to adopt any provision
         inconsistent with, this Article TWELFTH.

              THIRTEENTH.  Special meetings of stockholders may be called
         at any time by only the Chairman of the Board of Directors, the
         Chief Executive Officer (or if there is no Chief Executive
         Officer, the President) or the Board of Directors.  Business
         transacted at any special meeting of stockholders shall be limited
         to matters relating to the purpose or purposes stated in the
         notice of meeting.  Notwithstanding any other provision of law,
         this Amended and Restated Certificate of Incorporation or the By-
         Laws of the Corporation, each as amended, and notwithstanding the
         fact that a lesser percentage may be specified by law, the
         affirmative vote of the holders of at least seventy-five percent
         (75%) of the shares of capital stock of the Corporation issued and
         outstanding and entitled to vote shall be required to amend or
         repeal, or to adopt any provision inconsistent with, this
         Article THIRTEENTH.

         Officer, the President) or the Board of Directors.  Business
         transacted at any special meeting of stockholders shall be limited
         to matters relating to the purpose or purposes stated in the
         notice of meeting.

              1.4   Notice of Meetings.  Except as otherwise provided by

         meeting, except when a different vote is required by express

              1.10  Nomination of Directors.  Only persons who are
                    -----------------------
         nominated in accordance with the following procedures shall be
         eligible for election as directors.  Nomination for election to
         the Board of Directors of the corporation at a meeting of
         stockholders may be made by the Board of Directors or by any
         stockholder of the corporation entitled to vote for the election
         of directors at such meeting who complies with the notice
         procedures set forth in this Section 1.10.  Such nominations,
         other than those made by or on behalf of the Board of Directors,
         shall be made by notice in writing delivered or mailed by first
         class United States mail, postage prepaid, to the Secretary, and
         received not less than 60 days nor more than 90 days prior to such
         meeting; provided, however, that if less than 70 days' notice or
         prior public disclosure of the date of the meeting is given to
         stockholders, such nomination shall have been mailed or delivered
         to the Secretary not later than the close of business on the 10th
         day following the date on which the notice of the meeting was
         mailed or such public disclosure was made, whichever occurs first.
         Such notice shall set forth (a) as to each proposed nominee (i)
         the name, age, business address and, if known, residence address
         of each such nominee, (ii) the principal occupation or employment
         of each such nominee, (iii) the number of shares of stock of the

         appear on the corporation's books, of such stockholder and (ii)

         eligibility of such proposed nominee to serve as a director of the
         corporation.

              The chairman of the meeting may, if the facts warrant,
         determine and declare to the meeting that a nomination was not
         made in accordance with the foregoing procedure, and if he should
         so determine, he shall so declare to the meeting and the defective
         nomination shall be disregarded.

         to be properly brought before an annual meeting by a stockholder,
         if such business relates to the election of directors of the
         corporation, the procedures in Section 1.10 must be complied with.
         If such business relates to any other matter, the stockholder must
         have given timely notice thereof in writing to the Secretary.  To
         be timely, a stockholder's notice must be delivered to or mailed
         and received at the principal executive offices of the corporation
         not less than 60 days nor more than 90 days prior to the meeting;
         provided, however, that in the event that less than 70 days'

         By-Laws to the contrary, no business shall be conducted at any


                                        -4-
<PAGE>
 
         annual meeting except in accordance with the procedures set forth
         in this Section 1.11 and except that any stockholder proposal
         which complies with Rule 14a-8 of the proxy rules (or any
         successor provision) promulgated under the Securities Exchange Act
         of 1934, as amended, and is to be included in the corporation's
         proxy statement for an annual meeting of stockholders shall be
         deemed to comply with the requirements of this Section 1.11.

              The chairman of the meeting shall, if the facts warrant,
         determine and declare to the meeting that business was not
         properly brought before the meeting in accordance with the
         provisions of this Section 1.11, and if he should so determine,
         the chairman shall so declare to the meeting that any such
         business not properly brought before the meeting shall not be
         transacted.

              1.12  Action without Meeting.  Stockholders may not take any

         action by written consent in lieu of a meeting.

              1.13  Organization.  The Chairman of the Board, or in his
                    ------------
         absence the Vice Chairman of the Board designated by the Chairman
         of the Board, or the President, in the order named, shall call
         meetings of the stockholders to order, and shall act as chairman
         of such meeting; provided, however, that the Board of Directors
                          --------
         may appoint any stockholder to act as chairman of any meeting in
         the absence of the Chairman of the Board.  The Secretary of the

                                ---------------------


              2.1   General Powers.  The business and affairs of the
                    --------------
         corporation shall be managed by or under the direction of a Board
         of Directors, who may exercise all of the powers of the
         corporation except as otherwise provided by law, the Certificate
         of Incorporation or these By-Laws.  In the event of a vacancy in
         the Board of Directors, the remaining directors, except as
         otherwise provided by law, may exercise the powers of the full
         Board until the vacancy is filled.

              2.2   Number; Election and Qualification.  The number of
                    ----------------------------------
         directors which shall constitute the whole Board of Directors
         shall be determined by resolution of the Board of Directors, but
         in no event shall be less than three.  The number of directors may
         be decreased at any time and from time to time by a majority of


                                        -5-
<PAGE>
 
         the directors then in office, but only to eliminate vacancies
         existing by reason of the death, resignation, removal or
         expiration of the term of one or more directors.  The directors
         shall be elected at the annual meeting of stockholders by such
         stockholders as have the right to vote on such election.
         Directors need not be stockholders of the corporation.

              2.3   Classes of Directors.  The Board of Directors shall be
                    --------------------
         and is divided into three classes:  Class I, Class II and
         Class III.  No one class shall have more than one director more
         than any other class.  If a fraction is contained in the quotient
         arrived at by dividing the designated number of directors by
         three, then, if such fraction is one-third, the extra director
         shall be a member of Class I, and if such fraction is two-thirds,
         one of the extra directors shall be a member of Class I and one of
         the extra directors shall be a member of Class II, unless
         otherwise provided from time to time by resolution adopted by the
         Board of Directors.

              2.4   Terms of Office.  Each director shall serve for a term
                    ---------------
         ending on the date of the third annual meeting following the
         annual meeting at which such director was elected; provided, that
                                                            -------- 
         each initial director in Class I shall serve for a term ending on
         the date of the annual meeting of stockholders in 1997; each
         initial director in Class II shall serve for a term ending on the
         date of the annual meeting of stockholders in 1998; and each
         initial director in Class III shall serve for a term ending on the
         date of the annual meeting of stockholders in 1999; and provided
         further, that the term of each director shall be subject to the
         -------
         election and qualification of his successor and to his earlier
         death, resignation or removal.

              2.5   Allocation of Directors Among Classes in the Event of
                    -----------------------------------------------------
         Increases or Decreases in the Number of Directors.  In the event
         ------------------------------------------------- 
         of any increase or decrease in the authorized number of directors,
         (i) each director then serving as such shall nevertheless continue
         as a director of the class of which he is a member and (ii) the
         newly created or eliminated directorships resulting from such
         increase or decrease shall be apportioned by the Board of
         Directors among the three classes of directors so as to ensure
         that no one class has more than one director more than any other
         class.  To the extent possible, consistent with the foregoing
         rule, any newly created directorships shall be added to those
         classes whose terms of office are to expire at the latest dates
         following such allocation, and any newly eliminated directorships
         shall be subtracted from those classes whose terms of offices are
         to expire at the earliest dates following such allocation, unless
         otherwise provided from time to time by resolution adopted by the
         Board of Directors.

         enlargement of the Board, shall be filled only by vote of a
         majority of the directors then in office, although less than a
         quorum, or by a sole remaining director.  A director elected to
         fill a vacancy shall be elected for the unexpired term of his
         predecessor in office, and a director chosen to fill a position
         resulting from an increase in the number of directors shall hold
         office until the next election of the class for which such

         determined from time to time by the Board of Directors; provided
         that any director who is absent when such a determination is made
         shall be given notice of the determination.  A regular meeting of

         known business or home address at least 72 hours in advance of the

         quorum shall be reduced by one for each such director so
         disqualified; provided, however, that in no case shall less than
         one-third (1/3) of the number so fixed constitute a quorum.  In
         the absence of a quorum at any such meeting, a majority of the
         directors present may adjourn the meeting from time to time
         without further notice other than announcement at the meeting,
         until a quorum shall be present.

5.   Stock Available for Awards
     --------------------------

     (a) Subject to adjustment under subsection (b) below, Awards may be made
under the Plan for up to 1,000,000 shares of Common Stock. If any Award in
respect of shares of Common Stock expires or is terminated unexercised or is
forfeited for any reason or settled in a manner that results in fewer shares
outstanding than were initially awarded, the shares subject to such Award or so
surrendered, as the case may be, to the extent of such expiration, termination,
forfeiture or decrease, shall again be available for award under the Plan,
subject, however, in the case of Incentive Stock Options, to any limitation
required under the Code and provided that shares made available pursuant to this
sentence shall be available for Awards to Reporting Persons only to the extent
consistent with Rule 16b-3. Shares issued under the Plan may consist in whole or
in part of authorized but unissued shares or treasury shares.

     (b) In the event that the Board, in its sole discretion, determines that
any stock dividend, extraordinary cash dividend, recapitalization,
reorganization, merger, consolidation, split-up, spin-off, combination or other
similar transaction affects the Common Stock such that an adjustment is required
in order to

                                      -3-
<PAGE>
 
preserve the benefits or potential benefits intended to be made available under
the Plan, then the Board, subject, in the case of Incentive Stock Options, to
any limitation required under the Code, shall equitably adjust any or all of (i)
the number and kind of shares in respect of which Awards may be made under the
Plan, (ii) the number and kind of shares subject to outstanding Awards, and
(iii) the award, exercise or conversion price with respect to any of the
foregoing, and if considered appropriate, the Board may make provision for a
cash payment with respect to an outstanding Award, provided that after an IPO,
the number of shares subject to any Award shall always be a whole number.

     (c) The Board may grant Awards under the Plan in substitution for stock and
stock based awards held by employees of another corporation who concurrently
become employees of the Company as a result of a merger or consolidation of the
employing corporation with the Company (or a subsidiary of the Company) or the
acquisition by the Company (or a subsidiary of the Company) of property or stock
of the employing corporation. The substitute Awards shall be granted on such
terms and conditions as the Board considers appropriate in the circumstances.

     (d) Subject to adjustment under Section 5(b), the maximum number of shares
with respect to which an Award may be granted to any employee under the Plan
shall not exceed 300,000 per calendar year. For purposes of calculating such
maximum number, (a) an Award shall continue to be treated as outstanding
notwithstanding its repricing, cancellation or expiration and (b) the repricing
of an outstanding Award or issuance of a new Award in substitution for a
cancelled Award shall be deemed to constitute the grant of a new additional
Award separate from the original grant of the Award that is repriced or
cancelled.

6.   Stock Options
     -------------

     (a)  General
          -------

            (i) Subject to the provisions of the Plan, the Board may award
Incentive Stock Options and Nonstatutory Stock Options, and determine the number
of shares of Common Stock to be covered by each Option, the option price of such
Option and the conditions and limitations applicable to the exercise of such
Option. The terms and conditions of Incentive Stock Options shall be subject to
and comply with Section 422 of the Code, or any successor provision, and any
regulations thereunder.

            (ii) The Board shall establish the exercise price at the time each
Option is awarded. In the case of Incentive Stock

                                      -4-
<PAGE>
 
Options, such price shall not be less than 100% of the Fair Market Value of the
Common Stock on the date of award.

            (iii) Each Option shall be exercisable at such times and subject to
such terms and conditions as the Board may specify in the applicable Award or
thereafter. The Board may impose such conditions with respect to the exercise of
Options, including conditions relating to applicable federal or state securities
laws, as it considers necessary or advisable.

            (iv) Options granted under the Plan may provide for the payment of
the exercise price by delivery of cash or check in an amount equal to the
exercise price of such Options or, to the extent permitted by the Board at or
after the award of the Option, by (A) delivery of shares of Common Stock owned
by the optionee for at least six months (or such shorter period as is approved
by the Board), valued at their Fair Market Value, (B) delivery of a promissory
note of the optionee to the Company on terms determined by the Board, (C)
delivery of an irrevocable undertaking by a broker to deliver promptly to the
Company sufficient funds to pay the exercise price or delivery of irrevocable
instructions to a broker to deliver promptly to the Company cash or a check
sufficient to pay the exercise price, (D) payment of such other lawful
consideration as the Board may determine, or (E) any combination of the
foregoing.

            (v) The Board may provide for the automatic award of an Option upon
the delivery of shares to the Company in payment of the exercise price of an
Option for up to the number of shares so delivered.

            (vi) The Board may at any time accelerate the time at which all or
any part of an Option may be exercised.

     (b)  Incentive Stock Options
          -----------------------

          Options granted under the Plan which are intended to be Incentive
Stock Options shall be subject to the following additional terms and conditions:

            (i) All Incentive Stock Options granted under the Plan shall, at the
time of grant, be specifically designated as such in the option agreement
covering such Incentive Stock Options. The Option exercise period shall not
exceed ten years from the date of grant.

            (ii) If any employee to whom an Incentive Stock Option is to be
granted under the Plan is, at the time of the grant of such option, the owner of
stock possessing more than 10% of the

                                      -5-
<PAGE>
 
total combined voting power of all classes of stock of the Company (after taking
into account the attribution of stock ownership rule of Section 424(b) and of
the Code), then the following special provisions shall be applicable to the
Incentive Stock Option granted to such individual:

               (x) The purchase price per share of the Common Stock subject to
     such Incentive Stock Option shall not be less than 110% of the Fair Market
     Value of one share of Common Stock at the time of grant; and

               (y) The option exercise period shall not exceed five years from
     the date of grant.

            (iii) For so long as the Code shall so provide, options granted to
any employee under the Plan (and any other incentive stock option plans of the
Company) which are intended to constitute Incentive Stock Options shall not
constitute Incentive Stock Options to the extent that such options, in the
aggregate, become exercisable for the first time in any one calendar year for
shares of Common Stock with an aggregate Fair Market Value (determined as of the
respective date or dates of grant) of more than $100,000.

            (iv) No Incentive Stock Option may be exercised unless, at the time
of such exercise, the Participant is, and has been continuously since the date
of grant of his or her Option, employed by the Company, except that:

               (x) an Incentive Stock Option may be exercised within the period
     of three months after the date the Participant ceases to be an employee of
     the Company (or within such lesser period as may be specified in the
     applicable option agreement), provided, that the agreement with respect to
                                   --------
     such Option may designate a longer exercise period and that the exercise
     after such three-month period shall be treated as the exercise of a
     Nonstatutory Stock Option under the Plan;

               (y) if the Participant dies while in the employ of the Company,
     or within three months after the Participant ceases to be such an employee,
     the Incentive Stock Option may be exercised by the Participant's Designated
     Beneficiary within the period of one year after the date of death (or
     within such lesser period as may be specified in the applicable Option
     agreement); and

               (z) if the Participant becomes disabled (within the meaning of
     Section 22(e)(3) of the Code or any successor

                                      -6-
<PAGE>
 
     provision thereto) while in the employ of the Company, the Incentive Stock
     Option may be exercised within the period of one year after the date of
     death (or within such lesser period as may be specified in the applicable
     Option agreement).

For all purposes of the Plan and any Option granted hereunder, "employment"
shall be defined in accordance with the provisions of Section 1.421-7(h) of the
Income Tax Regulations (or any successor regulations). Notwithstanding the
foregoing provisions, no Incentive Stock Option may be exercised after its
expiration date.

            (v) Incentive Stock Options shall not be assignable or transferable
by the person to whom they are granted, either voluntarily or by operation of
law, except by will or the laws of descent and distribution, and, during the
life of the optionee, shall be exercisable only by the optionee.

7.   Stock Appreciation Rights
     -------------------------

     (a) The Board may grant SARs entitling recipients on exercise of the SAR to
receive an amount, in cash or Common Stock or a combination thereof (such form
to be determined by the Board), determined in whole or in part by reference to
appreciation in the Fair Market Value of the Common Stock between the date of
the Award and the exercise of the Award. A SAR shall entitle the Participant to
receive, with respect to each share of Common Stock as to which the SAR is
exercised, the excess of the share's Fair Market Value on the date of exercise
over its Fair Market Value on the date the SAR was granted. The Board may also
grant SARs that provide that, following a change in control of the Company (as
defined by the Board at the time of the Award), the holder of such SAR will be
entitled to receive, with respect to each share of Common Stock subject to the
SAR, an amount equal to the excess of a specified value (which may include an
average of values) for a share of Common Stock during a period preceding such
change in control over the Fair Market Value of a share of Common Stock on the
date the SAR was granted.

     (b) SARs may be granted in tandem with, or independently of, Options
granted under the Plan. A SAR granted in tandem with an Option which is not an
Incentive Stock Option may be granted either at or after the time the Option is
granted. A SAR granted in tandem with an Incentive Stock Option may be granted
only at the time the Option is granted.

     (c) When SARs are granted in tandem with Options, the following provisions
will apply:

                                      -7-
<PAGE>
 
          (i) The SAR will be exercisable only at such time or times, and to the
extent, that the related Option is exercisable and will be exercisable in
accordance with the procedure required for exercise of the related Option.

          (ii) The SAR will terminate and no longer be exercisable upon the
termination or exercise of the related Option, except that a SAR granted with
respect to less than the full number of shares covered by an Option will not be
reduced until the number of shares as to which the related Option has been
exercised or has terminated exceeds the number of shares not covered by the SAR.

          (iii) The Option will terminate and no longer be exercisable upon the
exercise of the related SAR.

          (iv) The SAR will be transferable only with the related Option.

          (v) A SAR granted in tandem with an Incentive Stock Option may be
exercised only when the market price of the Common Stock subject to the Option
exceeds the exercise price of such Option.

     (d) A SAR not granted in tandem with an Option will become exercisable at
such time or times, and on such conditions, as the Board may specify.

     (e) The Board may at any time accelerate the time at which all or any part
of the SAR may be exercised.

8.   Performance Shares
     ------------------

     (a) The Board may make Performance Share Awards entitling recipients to
acquire shares of Common Stock upon the attainment of specified performance
goals. The Board may make Performance Share Awards independent of or in
connection with the granting of any other Award under the Plan. The Board in its
sole discretion shall determine the performance goals applicable under each such
Award, the periods during which performance is to be measured, and all other
limitations and conditions applicable to the awarded Performance Shares;
provided, however, that the Board may rely on the performance goals and other
standards applicable to other performance plans of the Company in setting the
standards for Performance Share Awards under the Plan.

     (b) Performance Share Awards and all rights with respect to such Awards may
not be sold, assigned, transferred, pledged or otherwise encumbered.

                                      -8-
<PAGE>
 
     (c) A Participant receiving a Performance Share Award shall have the rights
of a stockholder only as to shares actually received by the Participant under
the Plan and not with respect to shares subject to an Award but not actually
received by the Participant. A Participant shall be entitled to receive a stock
certificate evidencing the acquisition of shares of Common Stock under a
Performance Share Award only upon satisfaction of all conditions specified in
the agreement evidencing the Performance Share Award.

     (d) The Board may at any time accelerate or waive any or all of the goals,
restrictions or conditions imposed under any Performance Share Award.

9.   Restricted and Unrestricted Stock
     ---------------------------------

     (a) The Board may grant Restricted Stock Awards entitling recipients to
acquire shares of Common Stock, subject to the right of the Company to
repurchase all or part of such shares at their purchase price (or to require
forfeiture of such shares if purchased at no cost) from the recipient in the
event that conditions specified by the Board in the applicable Award are not
satisfied prior to the end of the applicable Restricted Period or Restricted
Periods established by the Board for such Award. Conditions for repurchase (or
forfeiture) may be based on continuing employment or service or achievement of
pre-established performance or other goals and objectives.

     (b) Shares of Restricted Stock may not be sold, assigned, transferred,
pledged or otherwise encumbered, except as permitted by the Board, during the
applicable Restricted Period. Shares of Restricted Stock shall be evidenced in
such manner as the Board may determine. Any certificates issued in respect of
shares of Restricted Stock shall be registered in the name of the Participant
and, unless otherwise determined by the Board, deposited by the Participant,
together with a stock power endorsed in blank, with the Company (or its
designee). At the expiration of the Restricted Period, the Company (or such
designee) shall deliver such certificates to the Participant or if the
Participant has died, to the Participant's Designated Beneficiary.

     (c) The Board may, in its sole discretion, grant (or sell at a purchase
price determined by the Board, which shall not be lower than 85% of Fair Market
Value on the date of sale) to Participants shares of Common Stock free of any
restrictions under the Plan ("Unrestricted Stock").

     (d) The purchase price for each share of Restricted Stock and Unrestricted
Stock shall be determined by the Board of

                                      -9-
<PAGE>
 
Directors. Such purchase price may be paid in the form of past services or such
other lawful consideration as is determined by the Board.

     (e) The Board may at any time accelerate the expiration of the Restricted
Period applicable to all, or any particular, outstanding shares of Restricted
Stock.

10.  General Provisions Applicable to Awards
     ---------------------------------------

     (a) Applicability of Rule 16b-3. Those provisions of the Plan which make an
         ---------------------------
express reference to Rule 16b-3 shall apply to the Company only at such time as
the Company's Common Stock is registered under the Exchange Act, or any
successor provision, and then only to Reporting Persons.

     (b) Reporting Person Limitations. Notwithstanding any other provision of
         ----------------------------
the Plan, to the extent required to qualify for the exemption provided by Rule
16b-3, (i) any Option, SAR, Performance Share Award or other similar right
related to an equity security issued under the Plan to a Reporting Person shall
not be transferable other than by will or the laws of descent and distribution
or pursuant to a qualified domestic relations order as defined by the Code or
Title I or the Employee Retirement Income Security Act ("ERISA"), or the rules
thereunder, and shall be exercisable during the Participant's lifetime only by
the Participant or the Participant's guardian or legal representative, and (ii)
the selection of a Reporting Person as a Participant and the terms of his or her
Award shall be determined only in accordance with the applicable provisions of
Rule 16b-3.

     (c) Documentation. Each Award under the Plan shall be evidenced by an
         -------------
instrument delivered to the Participant specifying the terms and conditions
thereof and containing such other terms and conditions not inconsistent with the
provisions of the Plan as the Board considers necessary or advisable. Such
instruments may be in the form of agreements to be executed by both the Company
and the Participant, or certificates, letters or similar documents, acceptance
of which will evidence agreement to the terms thereof and of this Plan.

     (d) Board Discretion. Except as otherwise provided by the Plan, each type
         ----------------
of Award may be made alone, in addition to or in relation to any other type of
Award. The terms of each type of Award need not be identical, and the Board need
not treat Participants uniformly. Except as otherwise provided by the Plan or a
particular Award, any determination with respect to an Award may be made by the
Board at the time of award or at any time thereafter.

                                     -10-
<PAGE>
 
     (e) Termination of Status. Subject to the provisions of Section 6(b)(iv),
         --------------------- 
the Committee shall determine the effect on an Award of the disability, death,

other status of a Participant and the extent to which, and the period during
which, the Participant's legal representative, guardian or Designated
Beneficiary may exercise rights under such Award.

     (f) Mergers, Etc. In the event of a consolidation, merger or other
         ------------
reorganization in which all of the outstanding shares of Common Stock are
exchanged for securities, cash or other property of any other corporation or
business entity (an "Acquisition") or in the event of a liquidation of the
Company, the Board of Directors of the Company, or the board of directors of any
corporation assuming the obligations of the Company, may, in its discretion,
take any one or more of the following actions as to outstanding Awards: (i)
provide that such Awards shall be assumed, or substantially equivalent Awards
shall be substituted, by the acquiring or succeeding corporation (or an
affiliate thereof) on such terms as the Board determines to be appropriate, (ii)
upon written notice to Participants, provide that all unexercised Options or
SARs will become exercisable in full and will terminate immediately prior to the
consummation of such transaction except to the extent exercised by the
Participant within a specified period following the date of such notice, (iii)
in the event of an Acquisition under the terms of which holders of the Common
Stock of the Company will receive upon consummation thereof a cash payment for
each share surrendered in the Acquisition (the "Acquisition Price"), make or
provide for a cash payment to each Participant equal to the difference between
(A) the Acquisition Price times the number of shares of Common Stock subject to
outstanding Options or SARs of such Participant (to the extent such Options or
SARs have exercise prices not in excess of the Acquisition Price) and (B) the
aggregate exercise price of all such outstanding Options or SARs, in exchange
for the termination of all such Options and SARs held by such Participants, and
(iv) provide that all or any outstanding Awards shall become exercisable or
realizable in full prior to the effective date of such Acquisition.

     (g) Withholding. The Participant shall pay to the Company, or make
         -----------
provision satisfactory to the Board for payment of, any taxes required by law to
be withheld in respect of Awards under the Plan no later than the date of the
event creating the tax liability. In the Board's discretion, and subject to such
conditions as the Board may establish, such tax obligations may be paid in whole
or in part in shares of Common Stock, including shares retained from the Award
creating the tax obligation, valued at their Fair Market Value. The Company may,
to the extent

                                        -11-
<PAGE>
 
permitted by law, deduct any such tax obligations from any payment of any kind
otherwise due to the Participant.

     (h) Foreign Nationals. Awards may be made to Participants who are foreign
         -----------------
nationals or employed outside the United States on such terms and conditions
different from those specified in the Plan as the Board considers necessary or
advisable to achieve the purposes of the Plan or comply with applicable laws.

     (i) Amendment of Award. The Board may amend, modify or terminate any
         ------------------
outstanding Award, including substituting therefor another Award of the same or
a different type, changing the date of exercise or realization and converting an
Incentive Stock Option to a Nonstatutory Stock Option, provided that the
Participant's consent to such action shall be required unless the Board
determines that the action, taking into account any related action, would not
materially and adversely affect the Participant.

     (j) Cancellation and New Grant of Options. The Board of Directors shall
         -------------------------------------
have the authority to effect, at any time and from time to time, with the

Common Stock and having an option exercise price per share which may be lower or
higher than the exercise price per share of the cancelled Options or (ii) the
amendment of the terms of any and all outstanding Options under the Plan to
provide an option exercise price per share which is higher or lower than the
then current exercise price per share of such outstanding Options.

     (k) Conditions on Delivery of Stock. The Company will not be obligated to
         -------------------------------
deliver any shares of Common Stock pursuant to the Plan or to remove
restrictions from shares previously delivered under the Plan (i) until all
conditions of the Award have been satisfied or removed, (ii) until, in the
opinion of the Company's counsel, all applicable federal and state laws and
regulations have been complied with, (iii) if the outstanding Common Stock is at
the time listed on any stock exchange, until the shares to be delivered have
been listed or authorized to be listed on such exchange upon official notice of
notice of issuance, and (iv) until all other legal matters in connection with
the issuance and delivery of such shares have been approved by the Company's
counsel. If the sale of Common Stock has not been registered under the
Securities Act of 1933, as amended, the Company may require, as a condition to
exercise of the Award, such representations or agreements as the Company may
consider appropriate to avoid violation of such Act and may require that

11.  Miscellaneous
     -------------

     (a) No Right To Employment or Other Status. No person shall have any claim
         --------------------------------------
or right to be granted an Award, and the grant of an Award shall not be
construed as giving a Participant the right to continued employment or service
for the Company. The Company expressly reserves the right at any time to dismiss
a Participant free from any liability or claim under the Plan, except as
expressly provided in the applicable Award.

     (b) No Rights As Stockholder. Subject to the provisions of the applicable
         ------------------------
Award, no Participant or Designated Beneficiary shall have any rights as a
stockholder with respect to any shares of Common Stock to be distributed under
the Plan until he or she becomes the record holder thereof.

     (c) Exclusion from Benefit Computations. No amounts payable upon exercise
         -----------------------------------
of Awards granted under the Plan shall be considered salary, wages or
compensation to Participants for purposes of determining the amount or nature of
benefits that Participants are entitled to under any insurance, retirement or
other benefit plans or programs of the Company.

     (d) Effective Date and Term. The Plan shall become effective upon the
         -----------------------
closing of the Company's initial public offering. No Award granted under the
Plan shall become effective until the Plan shall have been approved by the
Company's stockholders. If such stockholder approval is not obtained within
twelve months after the date of the Board's adoption of the Plan, no Options
previously granted under the Plan shall be deemed to be Incentive Stock Options
and no Incentive Stock Options shall be granted thereafter. No Award may be made
under the Plan after May [  ], 2006, but Awards previously granted may extend
beyond that date.

     (e) Amendment of Plan. The Board may amend, suspend or terminate the Plan
         -----------------
or any portion thereof at any time, provided that no amendment shall be made
without stockholder approval if such approval is necessary to comply with any
applicable tax or regulatory requirement, including any requirements for
compliance with Rule 16b-3. Amendments requiring stockholder approval shall
become effective when adopted by the Board of Directors, but no Incentive Stock
Option granted after the date of such amendment shall become exercisable (to the
extent that such amendment to the Plan was required to enable the Company to
grant such Incentive Stock Option to a particular Participant) unless and until
such

                                     -13-
<PAGE>
 
amendment shall have been approved by the Company's stockholders. If such
stockholder approval is not obtained within twelve months of the Board's
adoption of such amendment, any Incentive Stock Options granted on or after the
date of such amendment shall terminate to the extent that such amendment to the
Plan was required to enable the Company to grant such option to a particular
Participant.

     (f) Governing Law. The provisions of the Plan shall be governed by and
         -------------
interpreted in accordance with the laws of the State of Delaware.


                                       Adopted by the Board of Directors
                                       on May 29, 1996

                                     -14-

                                                                    EXHIBIT 10.3


                             CAMBRIDGE HEART, INC.

                       1996 EMPLOYEE STOCK PURCHASE PLAN



     The purpose of this Plan is to provide eligible employees of Cambridge
Heart, Inc. (the "Company") and certain of its subsidiaries with opportunities
to purchase shares of the Company's Common Stock (the "Common Stock"). One
Hundred Thousand (100,000) shares of Common Stock in the aggregate have been
approved for this purpose.

     1.   Administration. The Plan will be administered by the Company's Board
          --------------
of Directors (the "Board") or by a Committee appointed by the Board (the
"Committee"). The Board or the Committee has authority to make rules and
regulations for the administration of the Plan and its interpretation and
decisions with regard thereto shall be final and conclusive.

     2.   Eligibility. Participation in the Plan will neither be permitted nor
          -----------
denied contrary to the requirements of Section 423 of the Internal Revenue Code
of 1986, as amended (the "Code"), and regulations promulgated thereunder. All
employees of the Company, including directors who are employees, and all
employees of any subsidiary of the Company (as defined in Section 424(f) of the
Code) designated by the Board or the Committee from time to time (a "Designated
Subsidiary"), are eligible to participate in any one or more of the offerings of
Options (as defined below) to purchase Common Stock under the Plan, provided
that:

          (a)  they are regularly employed by the Company or a Designated
     Subsidiary for more than 20 hours a week and for more than five months in a
     calendar year; and

          (b)  they have been employed by the Company or a Designated Subsidiary
     for at least three months prior to enrolling in the Plan; and

          (c)  they are employees of the Company or a Designated Subsidiary on
     the first day of the applicable Plan Period (as defined below).

     No employee may be granted an option hereunder if such employee,
immediately after the option is granted, owns 5% or more of the total combined
voting power or value of the stock of the Company or any subsidiary. For
purposes of the preceding sentence, the attribution rules of Section 424(d) of
the Code shall apply in determining the stock ownership of an employee, and
<PAGE>
 
all stock which the employee has a contractual right to purchase shall be
treated as stock owned by the employee.

     3.   Offerings. The Company will make one or more offerings ("Offerings")
          ---------
to employees to purchase Common Stock under this Plan. The Board or the
Committee shall determine the commencement dates of each of the Offerings (the
"Offering Commencement Dates"). Each Offering Commencement Date will begin a
period (a "Plan Period") during which payroll deductions will be made and held
for the purchase of Common Stock at the end of the Plan Period. The Board or the
Committee shall choose a Plan Period of twelve (12) months or less for each of
the Offerings and may, at its discretion, choose a different Plan Period for
each Offering.

     4.   Participation. An employee eligible on the Offering Commencement Date
          -------------
of any Offering may participate in such Offering by completing and forwarding a
payroll deduction authorization form to the Controller of the Company at least
14 days prior to the applicable Offering Commencement Date. The form will
authorize a regular payroll deduction from the Compensation received by the
employee during the Plan Period. Unless an employee files a new form or
withdraws from the Plan, his deductions and purchases will continue at the same
rate for future Offerings under the Plan as long as the Plan remains in effect.
The term "Compensation" means the amount of money reportable on the employee's
Federal Income Tax Withholding Statement, excluding overtime, shift premium,
incentive or bonus awards, allowances and reimbursements for expenses such as
relocation allowances for travel expenses, income or gains on the exercise of
Company stock options or stock appreciation rights, and similar items, whether
or not shown on the employee's Federal Income Tax Withholding Statement, but
including, in the case of salespersons, sales commissions to the extent
determined by the Board or the Committee.

     5.   Deductions.  
          ----------

          (a)  The Company will maintain payroll deduction accounts for all
participating employees. With respect to any Offering made under this Plan, an
employee may authorize a payroll deduction in any dollar amount up to a maximum
of 10% of the Compensation he or she receives during the Plan Period or such
shorter period during which deductions from payroll are made. Payroll deductions
may be at the rate of 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9% or 10% of Compensation.

          (b)  No employee may be granted an Option which permits his rights to
purchase Common Stock under this Plan and any other stock purchase plan of the
Company and its subsidiaries, to accrue at a rate which exceeds $25,000 of the
fair market value of such


                                         -2-
<PAGE>
 
Common Stock (determined at the Offering Commencement Date of the Plan Period)
for each calendar year in which the Option is outstanding at any time.

     6.   Deduction Changes. An employee may decrease or discontinue his payroll
          -----------------
deduction once during any Plan Period by filing a new payroll deduction
authorization form. However, an employee may not increase his payroll deduction
during a Plan Period. If an employee elects to discontinue his payroll
deductions during a Plan Period, but does not elect to withdraw his funds
pursuant to Section 8 hereof, funds deducted prior to his election to
discontinue will be applied to the purchase of Common Stock on the Exercise Date
(as defined below).

     7.   Interest.  Interest will not be paid on any employee payroll deduction
          --------
          accounts, except to the extent that the Board or its Committee, in its
          sole discretion, elects to credit such accounts with interest at such
          per annum rate as it may from time to time determine.

     8.   Withdrawal of Funds. An employee may on any one occasion during a Plan
          -------------------
Period and for any reason withdraw all or part of the balance accumulated in the
employee's payroll deduction account. Any such withdrawal must be effected prior
to the close of business on the last day of the Plan Period. If the employee
withdraws all of such balance, the employee shall thereby withdraw from
participation in the Offering and may not begin participation again during the
remainder of the Plan Period. Any employee withdrawing all or part of such
balance may participate in any subsequent Offering in accordance with terms and
conditions established by the Board or the Committee, except that, unless
otherwise permitted under Section 16 of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), and the rules promulgated thereunder, any employee
who is also a director and/or officer of the Company within the meaning of
Section 16 of the Exchange Act may not (a) withdraw less than all of the balance
accumulated in such employee's payroll deduction account or (b) participate
again for a period of at least six months as provided in Rule 16b-3(d)(2)(i) or
any successor provision under the Exchange Act.

     9.   Purchase of Shares.  
          ------------------

          (a)  On the Offering Commencement Date of each Plan Period, the
Company will grant to each eligible employee who is then a participant in the
Plan an option (an "Option") to purchase on the last business day of such Plan
Period (the "Exercise Date"), at the Option Price hereinafter provided for, such
number of whole shares of Common Stock of the Company reserved for the purposes
of the Plan as does not exceed the number of shares

                                         -3-
<PAGE>
 
determined by dividing 15% of such employee's annualized Compensation for the
immediately prior six-month period by the price determined in accordance with
the formula set forth in the following paragraph but using the closing price on
the Offering Commencement Date of such Plan Period.

          (b)  The Option Price for each share purchased will be 85% of the
closing price of the Common Stock on (i) the first business day of such Plan
Period or (ii) the Exercise Date, whichever closing price shall be less. Such
closing price shall be (A) the closing price of the Common Stock on any national
securities exchange on which the Common Stock is listed, or (B) the closing
price of the Common Stock on the Nasdaq National Market ("Nasdaq") or (C) the
average of the closing bid and asked prices in the over-the-counter market,
whichever is applicable, as published in The Wall Street Journal. If no sales of
                                         -----------------------
Common Stock were made on such a day, the price of the Common Stock for purposes
of clauses (A) and (B) above shall be the reported price for the next preceding
day on which sales were made.

          (c)  Each employee who continues to be a participant in the Plan on
the Exercise Date shall be deemed to have exercised his Option at the Option
Price on such date and shall be deemed to have purchased from the Company the
number of full shares of Common Stock reserved for the purpose of the Plan that
his accumulated payroll deductions on such date will pay for pursuant to the
formula set forth above (but not in excess of the maximum number determined in
the manner set forth above).

          (d)  Any balance remaining in an employee's payroll deduction account
at the end of a Plan Period will be automatically refunded to the employee,
except that any balance which is less than the purchase price of one share of
Common Stock will be carried forward into the employee's payroll deduction
account for the following Offering, unless the employee elects not to
participate in the following Offering under the Plan, in which case the balance
in the employee's account shall be refunded.

     10.  Issuance of Certificates. Certificates representing shares of Common
          ------------------------
Stock purchased under the Plan may be issued only in the name of the employee,
in the name of the employee and another person of legal age as joint tenants
with rights of survivorship, or (in the Company's sole discretion) in the street
name of a brokerage firm, bank or other nominee holder designated by the
employee.

     11.  Rights on Retirement, Death or Termination of Employment. In the event
          --------------------------------------------------------
of a participating employee's termination of employment prior to the last
business day of a Plan Period (whether as a result of the employee's voluntary
or

                                         -4-
<PAGE>
 
involuntary termination, retirement, death or otherwise), no payroll deduction
shall be taken from any pay due and owing to the employee and the balance in the
employee's payroll deduction account shall be paid to the employee or, in the
event of the employee's death, (a) to a beneficiary previously designated in a
revocable notice signed by the employee (with any spousal consent required under
state law) or (b) in the absence of such a designated beneficiary, to the
executor or administrator of the employee's estate or (c) if no such executor or
administrator has been appointed to the knowledge of the Company, to such other
person(s) as the Company may, in its discretion, designate. If, prior to the
last business day of the Plan Period, the Designated Subsidiary by which an
employee is employed shall cease to be a subsidiary of the Company, or if the
employee is transferred to a subsidiary of the Company that is not a Designated
Subsidiary, the employee shall be deemed to have terminated employment for the
purposes of this Plan.

     12.  Optionees Not Stockholders. Neither the granting of an Option to an
          --------------------------
employee nor the deductions from his pay shall constitute such employee a
stockholder of the shares of Common Stock covered by an Option under this Plan
until such shares have been purchased by and issued to him.

     13.  Rights Not Transferable. Rights under this Plan are not transferable
          -----------------------
by a participating employee other than by will or the laws of descent and
distribution, and are exercisable during the employee's lifetime only by the
employee.

     14.  Application of Funds. All funds received or held by the Company under
          --------------------
this Plan may be combined with other corporate funds and may be used for any
corporate purpose.

     15.  Adjustment in Case of Changes Affecting Common Stock. In the event of
          ----------------------------------------------------
a subdivision of outstanding shares of Common Stock, or the payment of a
dividend in Common Stock, the number of shares approved for this Plan, and the
share limitation set forth in Section 9, shall be increased proportionately, and
such other adjustment shall be made as may be deemed equitable by the Board or
the Committee. In the event of any other change affecting the Common Stock, such
adjustment shall be made as may be deemed equitable by the Board or the
Committee to give proper effect to such event.

     16.  Merger.  
          ------

          (a)  If the Company shall at any time merge or consolidate with
another corporation and the holders of the capital stock of the Company
immediately prior to such merger or consolidation continue to hold at least 80%
by voting power of the

                                         -5-
<PAGE>
 
capital stock of the surviving corporation ("Continuity of Control"), the holder
of each Option then outstanding will thereafter be entitled to receive at the
next Exercise Date upon the exercise of such Option for each share as to which
such Option shall be exercised the securities or property which a holder of one
share of the Common Stock was entitled to upon and at the time of such merger,
and the Board or the Committee shall take such steps in connection with such
merger as the Board or the Committee shall deem necessary to assure that the
provisions of Section 15 shall thereafter be applicable, as nearly as reasonably
may be, in relation to the said securities or property as to which such holder
of such Option might thereafter be entitled to receive thereunder.

          (b)  In the event of a merger or consolidation of the Company with or
into another corporation which does not involve Continuity of Control, or of a
sale of all or substantially all of the assets of the Company while unexercised
Options remain outstanding under the Plan, (i) subject to the provisions of
clauses (ii) and (iii), after the effective date of such transaction, each
holder of an outstanding Option shall be entitled, upon exercise of such Option,
to receive in lieu of shares of Common Stock, shares of such stock or other
securities as the holders of shares of Common Stock received pursuant to the
terms of such transaction; or (ii) all outstanding Options may be cancelled by
the Board or the Committee as of a date prior to the effective date of any such
transaction and all payroll deductions shall be paid out to the participating
employees; or (iii) all outstanding Options may be cancelled by the Board or the
Committee as of the effective date of any such transaction, provided that notice
of such cancellation shall be given to each holder of an Option, and each holder
of an Option shall have the right to exercise such Option in full based on
payroll deductions then credited to his account as of a date determined by the
Board or the Committee, which date shall not be less than ten (10) days
preceding the effective date of such transaction.

          17.  Amendment of the Plan. The Board may at any time, and from time
               ---------------------
to time, amend this Plan in any respect, except that (a) if the approval of any
such amendment by the stockholders of the Company is required by Section 423 of
the Code or by Rule 16b-3 under the Exchange Act, such amendment shall not be
effected without such approval, and (b) in no event may any amendment be made
which would cause the Plan to fail to comply with Section 16 of the Exchange Act
and the rules promulgated thereunder, as in effect from time to time, or Section
423 of the Code.

          18.  Insufficient Shares. In the event that the total number of shares
               -------------------
of Common Stock specified in elections to be purchased

                                         -6-
<PAGE>
 
under any Offering plus the number of shares purchased under previous Offerings
under this Plan exceeds the maximum number of shares issuable under this Plan,
the Board or the Committee will allot the shares then available on a pro rata
basis.

     19.  Termination of the Plan. This Plan may be terminated at any time by
          -----------------------
the Board. Upon termination of this Plan all amounts in the payroll deduction
accounts of participating employees shall be promptly refunded.

     20.  Governmental Regulations.  
          ------------------------

          (a)  The Company's obligation to sell and deliver Common Stock under
this Plan is subject to listing on a national stock exchange or quotation on
Nasdaq and the approval of all governmental authorities required in connection
with the authorization, issuance or sale of such stock.

          (b)  The Plan shall be governed by the laws of the State of Delaware
except to the extent that such law is preempted by federal law.

          (c)  The Plan is intended to comply with the provisions of Rule 16b-3
promulgated under the Exchange Act. Any provision inconsistent with such Rule
shall to that extent be inoperative and shall not affect the validity of the
Plan.

     21.  Issuance of Shares. Shares may be issued upon exercise of an Option
          ------------------
from authorized but unissued Common Stock, from shares held in the treasury of
the Company, or from any other proper source.

     22.  Notification upon Sale of Shares. Each employee agrees, by entering
          --------------------------------
the Plan, to promptly give the Company notice of any disposition of shares
purchased under the Plan where such disposition occurs within two years after
the date of grant of the Option pursuant to which such shares were purchased.

     23.  Effective Date and Approval of Stockholders. The Plan shall take
          -------------------------------------------
effect upon the closing of the Company's initial public offering of Common Stock
pursuant to an effective registration statement under the Securities Act of
1933, as amended, subject to approval by the stockholders of the Company as
required by Rule 16b-3 under the Exchange Act and by Section 423 of the Code,

the Board.

              The purpose of this 1996 Director Stock Option Plan
         (the "Plan") of Cambridge Heart, Inc. (the "Company") is to
         encourage ownership in the Company by outside directors of the
         Company whose continued services are considered essential to the
         Company's future progress and to provide them with a further
         incentive to remain as directors of the Company.  

         2.   Administration.
              --------------

              The Board of Directors shall supervise and administer the
         Plan.  Grants of stock options under the Plan and the amount and
         nature of the awards to be granted shall be automatic in
         accordance with Section 5.  However, all questions concerning
         interpretation of the Plan or any options granted under it shall
         be resolved by the Board of Directors and such resolution shall be
         final and binding upon all persons having an interest in the Plan.

         the Company or any subsidiary of the Company and are not, as
         determined by the Board of Directors in its reasonable judgment,
         otherwise affiliated with the Company ("outside directors") shall
         be eligible to receive options under the Plan.  

         4.   Stock Subject to the Plan.
              -------------------------

              (a)  The maximum number of shares of the Company's Common
         Stock ("Common Stock"), which may be issued under the Plan shall
         be 100,000 shares, subject to adjustment as provided in Section 7.  

              (b)  If any outstanding option under the Plan for any reason
         expires or is terminated without having been exercised in full,
         the shares covered by the unexercised portion of such option shall
         again become available for issuance pursuant to the Plan.  

              (c)  All options granted under the Plan shall be non-
         statutory options not entitled to special tax treatment under

         share for each option described in clause (i) of Section 5(a)
         shall be equal to the last reported sale price of the Common Stock
         on the Nasdaq National Market on the Closing Date.  The option
         exercise price per share for each option described in clauses (ii)
         and (iii) of Section 5(a) shall be determined as follows:  (i) if
         the Common Stock is listed on the Nasdaq National Market or
         another nationally recognized exchange or trading system as of the
         Option Grant Date, the option exercise price shall be deemed to be
         the last reported sale price per share of Common Stock thereon on
         such date (or if no such price is reported on such date, such
         price on the nearest preceding date on which such a price is
         reported); and (ii) if the Common Stock is not listed on the
         Nasdaq National Market or another nationally recognized exchange
         or trading system as of the Option Grant Date, the exercise price
         per share shall be deemed to be the fair market value of the
         Common Stock as of the Option Grant Date as determined in good
         faith by the Board of Directors.  

              (c)  Options Non-Transferable.  To the extent required to
                   ------------------------
         qualify for the exemption provided by Rule 16b-3 under the
         Securities Exchange Act of 1934, as amended (the "Exchange
         Act"), any option granted under the Plan to an optionee shall not
         be transferable by the optionee other than by will or the laws of
         descent and distribution or pursuant to a qualified domestic
         relations order as defined by the Code or Title I of the Employee



                                         -2-

         Retirement Income Security Act, or the rules thereunder, and shall
         be exercisable during the optionee's lifetime only by the optionee
         or the optionee's guardian or legal representative.  

              (d)  Vesting Period.
                   --------------

                   (i)  General.  Each option described in clauses (i) and
                        -------
         (ii) of Section 5(a) shall vest in three equal, annual
         installments on the anniversary of the Option Grant Date.

                  (ii)  Acceleration Upon Change in Control.
                        -----------------------------------
         Notwithstanding the foregoing, each outstanding option granted
         under the Plan shall immediately become exercisable in full in the
         event a Change in Control (as defined in Section 8) of the Company
         occurs. 

              (e)  Termination.  Each option shall terminate, and may no
                   -----------
         longer be exercised, on the earlier of the (i) the date 10 years
         after the Option Grant Date or (ii) the date 60 days after the
         optionee ceases to serve as a director of the Company; provided
         that, in the event an optionee ceases to serve as a director due
         to his or her death or disability (within the meaning of
         Section 22(e)(3) of the Code or any successor provision), then the
         exercisable portion of the option may be exercised, within the
         period of 180 days following the date the optionee ceases to serve
         as a director (but in no event later than 10 years after the
         Option Grant Date), by the optionee or by the person to whom the
         option is transferred by will, by the laws of descent and
         distribution, or by written notice pursuant to Section 5(g).

              (f)  Exercise Procedure.  An option may be exercised only by
                   ------------------
         written notice to the Company at its principal office accompanied
         by payment in cash of the full consideration for the shares as to
         which the option is exercised.  

              (g)  Exercise by Representative Following Death of Director.
                   ------------------------------------------------------
         An optionee, by written notice to the Company, may designate one
         or more persons (and from time to time change such designation),
         including his or her legal representative, who, by reason of the
         optionee's death, shall acquire the right to exercise all or a
         portion of the option.  If the person or persons so designated
         wish to exercise any portion of the option, they must do so within
         the term of the option as provided herein.  Any exercise by a
         representative shall be subject to the provisions of the Plan.  

         6.   Limitation of Rights.
              --------------------

              (a)  No Right to Continue as a Director.   Neither the Plan,
                   ----------------------------------
         nor the granting of an option nor any other action taken pursuant
         to the Plan, shall constitute or be evidence of any agreement or


                                         -3-
<PAGE>
 
         understanding, express or implied, that the Company will retain
         the optionee as a director for any period of time.  

              (b)  No Stockholders' Rights for Options.  An optionee shall
                   -----------------------------------
         have no rights as a stockholder with respect to the shares covered
         by his or her option until the date of the issuance to him or her
         of a stock certificate therefor, and no adjustment will be made
         for dividends or other rights (except as provided in Section 7)
         for which the record date is prior to the date such certificate is
         issued.  

         7.   Adjustment Provisions for Mergers, Recapitalizations and
              --------------------------------------------------------
         Related Transactions.
         --------------------

              If, through or as a result of any merger, consolidation,
         reorganization, recapitalization, reclassification, stock
         dividend, stock split, reverse stock split, or other similar
         transaction, (i) the outstanding shares of Common Stock are
         exchanged for a different number or kind of securities of the
         Company or of another entity, or (ii) additional shares or new or
         different shares or other securities of the Company or of another
         entity are distributed with respect to such shares of Common
         Stock, the Board of Directors shall make an appropriate and
         proportionate adjustment in (x) the maximum number and kind of
         shares reserved for issuance under the Plan, (y) the number and
         kind of shares or other securities subject to then outstanding
         options under the Plan, and/or (z) the price for each share
         subject to any then outstanding options under the Plan (without
         changing the aggregate purchase price for such options), to the
         end that each option shall be exercisable, for the same aggregate
         exercise price, for such securities as such optionholder would
         have held immediately following such event if he had exercised
         such option immediately prior to such event.  No fractional shares
         will be issued under the Plan on account of any such adjustments.

         8.   Change in Control.  For purposes of the Plan, a "Change in
              -----------------
         Control" shall be deemed to have occurred only if any of the
         following events occurs:  (i) any "person", as such term is used
         in Sections 13(d) and 14(d) of the Exchange Act (other than the
         Company, any trustee or other fiduciary holding securities under
         an employee benefit plan of the Company, or any corporation owned
         directly or indirectly by the stockholders of the Company in
         substantially the same proportion as their ownership of stock of
         the Company), is or becomes the "beneficial owner" (as defined in
         Rule 13d-3 under the Exchange Act), directly or indirectly, of
         securities of the Company representing 50% or more of the combined
         voting power of the Company's then outstanding securities;
         (ii) the stockholders of the Company approve a merger or
         consolidation of the Company with any other corporation, other
         than a merger or consolidation which would result in the voting


                                         -4-
<PAGE>
 
         securities of the Company outstanding immediately prior thereto
         continuing to represent (either by remaining outstanding or by
         being converted into voting securities of the surviving entity)
         more than 50% of the combined voting power of the voting
         securities of the Company or such surviving entity outstanding
         immediately after such merger or consolidation; (iii) the
         stockholders of the Company approve a plan of complete liquidation
         of the Company or an agreement for the sale or disposition by the
         Company of all or substantially all of the Company's assets; or
         (iv) individuals who, on the date on which the Plan was adopted by
         the Board of Directors, constituted the Board of Directors of the
         Company, together with any new director whose election by the
         Board of Directors or nomination for election by the Company's
         stockholders was approved by a vote of at least a majority of the
         directors then still in office who were directors on the date on
         which the Plan was adopted by the Board of Directors or whose
         election or nomination was previously so approved, cease for any
         reason to constitute at least a majority of the Board of
         Directors. 

         9.   Modification, Extension and Renewal of Options.
              ----------------------------------------------

              The Board of Directors shall have the power to modify or
         amend outstanding options; provided, however, that no modification
         or amendment may (i) have the effect of altering or impairing any
         rights or obligations of any option previously granted without the
         consent of the optionee, or (ii) modify the number of shares of
         Common Stock subject to the option (except as provided in
         Section 7).  

         10.  Termination and Amendment of the Plan.
              -------------------------------------

              The Board of Directors may suspend, terminate or discontinue
         the Plan or amend it in any respect whatsoever; provided, however,
         that without approval of the stockholders of the Company, no
         amendment may (i) increase the number of shares subject to the
         Plan (except as provided in Section 7), (ii) materially modify the
         requirements as to eligibility to receive options under the Plan,
         or (iii) materially increase the benefits accruing to participants
         in the Plan; and provided further that the Board of Directors may
         not amend the provisions of Sections 3, 5(a) or 5(b) more
         frequently than once every six months, other than to comply with
         changes in the Code or the rules thereunder.  

         11.  Notice.
              ------

              Any written notice to the Company required by any of the
         provisions of the Plan shall be addressed to the Controller of the
         Company and shall become effective when it is received.

         granted under the Plan shall be null and void if the Plan is not
         so approved by the Company's stockholders.

                                       Adopted by the Board of Directors on
                                       May 29, 1996

     2.7  The Consulting Period shall terminate upon COHEN's death or in the

                       ARTICLE 3 - INTELLECTUAL PROPERTY

     3.1  Any enhancements, improvements, refinements or modifications to the
TECHNOLOGIES or IMPROVEMENTS, and any other inventions, conceived, or reduced to
practice, in whole or in part by COHEN in the context of his consulting activity
under this Agreement, shall be assigned to the Company.

     3.2  To the extent permissible under the terms of the Company's license
agreements with third parties or with COHEN, as the case may be, the Company
shall apply for, seek prompt issuance of, and maintain appropriate IMPROVEMENTS
patents and copyrights in the United States and appropriate foreign countries.
All such patents and copyrights shall be applied for in the name of the Company,
except as required by the terms of the Company's license agreements with third
parties or with COHEN, as the case may be.  The prosecution, filing and
maintenance of all IMPROVEMENTS copyrights, patents and applications therefor
shall be the responsibility of the Company; provided COHEN shall have reasonable
opportunities to advise the Company.  The Company may request COHEN to assist
the Company in preparing and prosecuting patent and copyright applications in
this regard, and COHEN agrees to do so.  To the extent that COHEN is requested
to assist the Company in preparing and prosecuting patent and copyright
applications during the Consulting Period, such assistance shall be part of
COHEN's consulting duties, and COHEN shall not be separately compensated
therefor.  In addition, in the event that the Company exercises its option
pursuant to Paragraph 2.2 hereof to extend the Noncompete Period beyond the
expiration or termination of the Consulting Period, the Company shall be
entitled to COHEN's assistance, without charge, in the preparation and

                                      -10-
<PAGE>
 
prosecution of IMPROVEMENTS patent and copyright applications up to an average
of not more than two days per month during such extended Noncompete Period.
Except as set forth herein, or in any employment agreement which may hereafter
be entered into between COHEN and the Company, COHEN shall be entitled to
receive reasonable consulting fees for his time spent assisting the Company in
preparing and prosecuting IMPROVEMENTS patent and copyright applications
hereunder.

     3.3  Payment of all fees and costs relating to the filing, prosecution, and
maintenance of IMPROVEMENTS patents and copyrights shall be the responsibility
of the Company.

     3.4  The Company is aware that COHEN is a university professor currently
employed by the Massachusetts Institute of Technology ("MIT") conducting
research in the fields of the TECHNOLOGIES, and that COHEN is obligated to
assist MIT in protecting inventions and copyrightable material developed by him
or in his laboratory at MIT, and to assist MIT in transferring such inventions
and copyrightable materials to third parties. In the event that it is unclear
whether a particular invention or copyrightable material in the nature of an
improvement to the TECHNOLOGIES is developed by COHEN in the context of his
consulting activity at the Company or in the context of his activities as an
employee of MIT or any other Not-for-Profit at which COHEN may be employed
during the Consulting Period, the Company will approach the Not-for-Profit in
good faith to negotiate a reasonable resolution.

     3.5  COHEN agrees not to reveal (except in discharge of a legal duty to do
so) confidential information and trade secrets of the Company relating to the
TECHNOLOGIES or any confidential information relating to the business of the
Company which is disclosed to him in the context of his consultancy or in

                                      -11-
<PAGE>
 
connection with his rights to receive royalties hereunder. Such confidential
information and trade secrets shall not be construed to include information:

          (a)  which is generally available to the public; and/or

          (b)  which through no act of COHEN becomes information generally
               available to the public; and/or

          (c)  which corresponds in substance to information furnished to COHEN
               by any third party having a lawful and unrestricted right to do
               so; and/or

          (d)  which corresponds to information forwarded by the Company to any
               third party on a non-confidential basis.

       ARTICLE 4 - CASH COMPENSATION; REIMBURSEMENT AND GRANT OF WARRANTS

     4.1  In consideration for his consulting services, the Company shall pay
COHEN a retainer of Seven-thousand-five-hundred dollars ($7,500) per month
during the Consulting Period.  The monthly retainer paid to COHEN may be
increased from time to time at the discretion of the Board of Directors of the
Company based upon corporate performance and COHEN's performance; provided,
however, that in no case in any given year shall the annual percentage increase
above the previous year's level be less than the sum of three percent (3%) plus
the annual percentage increase in the National Consumer Price Index.  In the
event that COHEN is granted the Sabbatical during the Consulting Period and the
number of days which COHEN is available to the Company is increased in
accordance with Pagraph 2.1 hereof, the amount of the monthly retainer fee paid
to COHEN shall be increased by five thousand ($5,000) per month during the
Sabbatical.  The Company shall be obligated to pay COHEN the monthly retainer
fee whether or not the Company utilizes COHEN's consulting services.  During the
Consulting Period, the retainer due to COHEN hereunder shall be paid monthly in
advance.

     4.2  The Company will pay for all of COHEN's travel and other out-of-pocket
expenses incurred in connection with his consulting activity, as well as

                                      -12-
<PAGE>
 
any expenses of a similar nature incurred by Cohen prior to the Effective Date
of this Agreement.  Upon request the Company will advance COHEN funds to cover
anticipated out-of-pocket expenses, and reimburse COHEN within five business
days of receipt of COHEN's invoices for his uncovered out-of-pocket expenses.

     4.3  As an inducement to COHEN to enter into this Agreement, the Company
hereby agrees that upon the execution and delivery of this Agreement by COHEN,
the Company shall issue to COHEN a common stock purchase warrant in the form of
Exhibit I hereto (the "Warrant") entitling COHEN to purchase a number of shares
of Common Stock, $.01 par value per share ("Common Stock"), of the Company, to
be determined as set forth in the Warrant (not to exceed 133,000 shares) at an
initial exercise price per share to be determined as set forth in the Warrant.

reasonable best efforts to bring PRODUCTS or PROCESSES for each of the
TECHNOLOGIES to market through an ongoing, thorough, vigorous and diligent
program for exploitation of the TECHNOLOGIES and IMPROVEMENTS and to continue
vigorous, ongoing, active, diligent marketing of the PRODUCTS or PROCESSES. Such

Company shall adhere to the following milestones:

          each of the TECHNOLOGIES and IMPROVEMENTS thereon and shall provide
          similar reports to COHEN on or before December 31 of each year.

          (b) The Company shall raise a minimum of Three Million Dollars
          ($3,000,000) in investment capital on or before May 31, 1993.

                                      -13-
<PAGE>
 
     5.3  Unless extended by mutual consent of the parties, the Company's
failure to perform in accordance with Paragraphs 5.1 and 5.2 above shall be
grounds for COHEN to terminate this Agreement upon written notice to the Company
specifying the ground for termination.  Any such termination based upon
Paragraph 5.1 or Paragraph 5.2(a) hereof shall become effective ninety (90) days
after the date of the notice of termination, unless the Company shall have cured
any such failure of performance prior to the expiration of such ninety (90) day
period, or unless COHEN shall have previously withdrawn in writing his notice of
termination.  Any such termination based upon Paragraph 5.2(b) hereof shall be
effective immediately.

                             ARTICLE 6 - ROYALTIES

     6.1  The Company agrees to pay COHEN royalties on TECHNOLOGIES PRIMARILY
LICENSED FROM THIRD PARTIES and IMPROVEMENTS thereon in consideration for
COHEN's assistance in the initial transfer to the Company of the TECHNOLOGIES
PRIMARILY LICENSED FROM THIRD PARTIES and his assistance in the development of
IMPROVEMENTS thereon, in the following manner:

          Running Royalties in an amount equal to One Percent (1%) of the NET
SALES related to TECHNOLOGIES PRIMARILY LICENSED FROM THIRD PARTIES and
IMPROVEMENTS thereon leased or sold by the Company. If the Company sublicenses,
or grants any rights to sublicense, the technology at arms length with an
unrelated company in which the Company holds no equity position, or rights to
acquire equity, to manufacture, sell and market PRODUCTS and/or PROCESSES
related to TECHNOLOGIES PRIMARILY LICENSED FROM THIRD PARTIES and IMPROVEMENTS
thereon in an arrangement in which the Company receives only cash compensation
and does not issue any equity or rights to acquire equity, then the Royalties
due COHEN from the Company shall be Seven Percent (7%) of gross revenue to the
Company from the Sublicensee for the sublicensing of the TECHNOLOGIES or

                                      -14-
<PAGE>
 
IMPROVEMENTS. In any other form of sublicense arrangement, the Royalties due
COHEN from the Company shall be determined by mutual agreement of COHEN and the
Company pursuant to Paragraph 10.4 hereof.  In the event of any assignment, the
Royalties or other payments due COHEN shall be determined pursuant to Paragraph
11.3 hereof.

     Notwithstanding the foregoing, Royalties in consideration of payments by
third parties to the Company for the granting of any rights to sublicense to the
TECHNOLOGIES or IMPROVEMENTS shall be due and payable to COHEN only if the
granting of such rights results in the third party entering into  a definitive
sublicense agreement with respect to the TECHNOLOGIES or IMPROVEMENTS to which
such rights were granted.

     6.2  Royalties due COHEN for OTHER TECHNOLOGIES and IMPROVEMENTS thereon
shall be governed by the terms of separate agreements between COHEN and the
Company in regard to such OTHER TECHNOLOGIES and IMPROVEMENTS thereon.

     6.3  No multiple royalties shall be payable because any PRODUCT or PROCESS,
its manufacture, use, lease and/or sale are or shall be covered by more than one
agreement between the Company and COHEN. If a PRODUCT or PROCESS is covered by
more than one agreement between the Company and COHEN than the largest royalty
due under any single agreement shall be applicable.

     6.4  All royalties due hereunder shall be paid in full, without deduction
of taxes or other fees which may be imposed upon the Company or its sublicensees
by any government; the payment of any such taxes or other fees shall be the
responsibility of the Company or its sublicensees.  Notwithstanding the
foregoing, the Company shall not be responsible for the payment of any taxes
which are based on COHEN's royalty or consulting income earned under this
Agreement, the payment of any such taxes shall be the responsibility of COHEN.

                                      -15-
<PAGE>
 
     6.5  Payment of royalties hereunder shall not be limited by the term of
COHEN's duty to consult hereunder.  The Company's obligations to pay royalties
hereunder are independent obligations of the Company arising out of the sale of
PRODUCTS and PROCESSES by the Company and its sublicensees.

     6.6  Royalty payments shall be paid in United States dollars in Waban,
Massachusetts, or at such other place as COHEN may reasonably designate
consistent with the laws and regulations controlling any foreign country.
Payments shall be made within sixty days after the end of each fiscal quarter of
the Company.   If any currency conversion shall be required in connection with
the payment of royalties hereunder, such conversion shall be made by using the
exchange rate prevailing at the Chase Manhattan Bank (N.A.) on the last business
day of the calendar quarterly reporting period to which such royalty payments
relate.

     6.7  In the event that the Company and COHEN disagree as to the revenue
base for the computation of Royalties due COHEN, the Company and COHEN shall
negotiate in good faith to resolve such disagreement.

                        ARTICLE 7 - REPORTS AND RECORDS

     7.1  The Company shall keep full, true and accurate books of account
containing all particulars that may be necessary for the purpose of showing the
amounts payable to COHEN hereunder. Said accurate books of account shall be kept

(3) years following the end of the calendar year to which they pertain, to the
inspection of COHEN or his agents for the purpose of verifying the Company's
royalty statement or compliance in other respects with this Agreement. COHEN
shall pay the cost of any such inspection, unless such inspection lead to the

                                      -16-
<PAGE>
 
discovery of a greater than ten percent (10%) discrepancy in reporting, in which
case the Company agrees to pay half the cost of such inspection.

     7.2  Within sixty (60) days after the end of each fiscal quarter of the
Company, the Company shall deliver to COHEN true and accurate reports certified
as correct by the Company's chief financial officer, giving such particulars of

the Company shall so report.

     7.4  On or before the ninetieth (90) day following the close of the
Company's fiscal year, the Company shall provide COHEN with the Company's
certified financial statements for the preceding fiscal year including, at a
minimum, a Balance Sheet and an Operating Statement certified to by the
Company's independent certified public accountants.

     7.5  The royalty payments set forth in this Agreement and amounts due under
Article 6 shall, if overdue, bear interest until payment at a per annum rate two
percent (2%) above the prime rate in effect at the Chase Manhattan Bank

                                      -17-
<PAGE>
 
(N.A.) on the due date. The payment of such interest shall not foreclose COHEN
from exercising any other rights he may have as a consequence of the lateness of
any payment.

     8.1  LICENSEE shall at all times during the term of this Agreement and

                              EMPLOYMENT AGREEMENT
                              --------------------

     EMPLOYMENT AGREEMENT, dated as of September 1, 1993, between CAMBRIDGE
HEART, INC., a Delaware corporation with offices c/o KBL Healthcare, Inc., 645
Madison Avenue, New York, New York 10022 (the "Company"), and JEFFREY M. ARNOLD
residing at 34 Bancroft Road, Wellesley, MA 02181 ("Employee").

     The Company desires to engage Employee to perform services for the Company
or, at the direction of the Company, any present or future parent or subsidiary
of the Company, and (subject to Section 11) any successor or assign of any of
them (the "Corporations") and Employee desires to perform such services, on the
terms and conditions hereinafter set forth.

     1.  Term
         ----

     The Company agrees to employ Employee, and Employee agrees to serve, on the
terms and conditions of this Agreement for a period commencing as of the date
hereof (the "Commencement Date") and ending five (5) years from such date, or
such shorter period as may be provided for herein.  The period during which
Employee is employed hereunder is hereafter referred to as the "Employment
Period."   Not later than three months prior to the fifth anniversary of the
Commencement Date, the Company shall notify the Employee whether it wishes to
extend the term of Employee's employment by the Company hereunder.

                                      -1-
<PAGE>
 
     2.  Duties and Services
         -------------------

     (a) During the Employment Period, Employee shall be employed by the Company
as its President and Chief Executive Officer, and shall also perform services
commensurate with such office in a responsible executive or managerial capacity
for any of the other Corporations as reasonably requested by the Company, which
duties shall be consistent with the provisions of the By-laws in effect on the
date hereof that relate to the duties of the President and Chief Executive
Officer.  In performance of his duties, Employee shall be subject to
the direction of the Board of Directors of the Company.  Employee agrees to his
employment as described in this Section 2 and agrees to devote his full business
time and attention to the performance of his duties under this Agreement, except
as provided in subparagraph (c) below and excepting disabilities, illness, and
vacation time as provided by Sections 3 and 4.  In performing his duties
hereunder, Employee shall be available for reasonable travel as the needs of the
Company require.  The principal place of employment of Employee hereunder shall
at all times during the term of this Agreement be in the greater Boston,
Massachusetts area, or other locations acceptable to Employee, in his sole
discretion.

     (b) During the Employment Period, the Company shall cause Employee to be
nominated to serve as a member of the Company's Board of Directors each time
that elections of the Board of Directors are held.

     (c) The Company acknowledges that (i) Employee has agreed to be available
to provide consulting services to his former employer, Momentum Software, Inc.
("Momentum"), at the rate of one day each month, if requested by Momentum, and
Employee will be required to attend meetings of the Board of Directors of
Momentum, for so long as Employee continues to be a member of the Board of
Directors of Momentum.  The Company agrees that Employee may continue

                                      -2-
<PAGE>
 
to provide consulting services to Momentum and to serve on Momentum's Board of
Directors, as described in the preceding sentence, during the Employment Period.
Notwithstanding anything to the contrary herein, although Employee shall provide
services as a full time employee, it is understood that Employee may (1) have
non full-time academic appointments; (2) participate in professional activities;
(3) be a member of the scientific or medical advisory board or the Board of
Directors of other companies; and (4) publish academic articles (collectively,
"Permitted Activities"); provided, however, that such Permitted Activities do
not interfere with Employee's duties to the Company, or result in a breach of
Sections 6, 7 or 8 of this Agreement; provided further, however, that prior to
accepting membership on the Board of Directors or the scientific or medical
advisory board of any other company, Employee shall obtain the consent of the
Company's Board of Directors, which consent shall not be unreasonably withheld.

     3.  Compensation; Benefits
         ----------------------

     (a) As compensation for his services hereunder, the Company shall pay
Employee, during the Employment Period, a base salary payable monthly at the
rate of $12,500 per month.  For each year of the Employment Period, Employee
shall be given an opportunity to earn a performance-based bonus in accordance
with an executive bonus plan approved by the Company's Board of Directors and
based on factors to be measured as of the end of each calendar year commencing
with the calendar year ending December 31, 1994; such bonus to be earned as of
December 31 of each such year and paid prior to January 31 of the following
year.  The amount of such performance-based bonuses shall be $25,000 for the
first two years of the Employment Period and $50,000 for each subsequent year of
the Employment Period.  To the extent that a calendar year for which a bonus is
payable hereunder includes years of the Employment Period for which different
rates of bonus may be earned, the amount of bonus payable for such year shall

                                      -3-
<PAGE>
 
be a blended amount.  Furthermore, the first such bonus, to be earned as of
December 31, 1994, shall be increased by the amount of bonus which could have
been earned by Employee during the period from the commencement of the
Employment Period to December 31, 1993, if the Company had a bonus plan in
effect during such period.  For all bonuses payable hereunder, in the event that
the Employee shall not be employed by the Company throughout an entire calendar
year for which a bonus is to be paid, the Employee shall be entitled to receive
only a pro rata share of such annual bonuses based upon the number of weeks
during such calendar year that the Employee was employed, calculated at the rate
of bonus in effect during such period that the Employee was employed.  The
Company shall review the Employee's performance and the performance of the
Company annually, and the Employee's salary may be increased, at the discretion
of the Company, on the basis of such review.

     (b)  Upon the commencement of the Employment Period, the Employee shall be
granted options to purchase an aggregate of 1,232,326 shares of Common Stock of
the Company, par value $.001 per share.  Of such options 1,050,000 shall have an
exercise price of at a price of $.01 per share, and 182,326 shall  be granted by
the Company as "incentive stock options" within the meaning of Section 422A of
the Internal Revenue Code of 1986, as amended, and have an exercise price of
$1.00 per share, which price, based on the $1.00 per share price that the
Company is concurrently offering shares of its Series A Convertible Preferred
Stock in a private placement, is in excess of the fair market value of the
Company's Common Stock.  Except as otherwise provided herein, such options shall
vest and become exercisable by the Employee at the rate of 210,000 shares per
year and 36,465.2 shares per year, respectively, over a period of five (5) years
from April 26, 1993, with options to purchase an aggregate of 246,465.2 shares
first becoming exercisable April 26, 1994.  To the

                                      -4-
<PAGE>
 
maximum extent conditions for eligibility under Rule 701(b) under the Securities
Act of 1933, as amended (the "Act"), are satisfied in connection with the grant
of such options or the sale of shares issuable upon exercise of such options (it
being acknowledged that such grant and such sale are pursuant to a written
contract relating to compensation), the Company shall comply promptly with the
notice requirements of Rule 702T under the Act and shall otherwise treat such
grant and sale as made pursuant to Rule 701.

     In the event that the Company terminates Employee's employment prior to
April 26, 1994 pursuant to Section 10(c) hereof, options to purchase 246,465.2
shares (which otherwise would become exercisable on April 26, 1994) shall vest
and become exercisable upon such termination.  In the event that the Company
terminates Employee's employment at any time on or after April 26, 1994 and
prior to April 26, 1998, pursuant to Section 10(c) hereof, the aggregate number
of options which shall be deemed to have vested prior to such date shall be a
number determined by multiplying 1,232,326 by a fraction, the numerator of which
shall be the number of months from April 26, 1993 to the effective date of the
termination of the Employment Period, and the denominator of which shall be 48;
provided, however, that in no case shall the aggregate number of options deemed
to have become vested exceed 1,232,326.  In lieu of the acceleration provided
for in the preceding sentence, in the event of the liquidation or Change of
Control (as defined below), of the Company, the Employee's vesting in the
options referred to herein shall accelerate to the next annual vesting date
following such liquidation or Change of Control, plus one year.

     All options and shares issuable upon exercise of options shall be adjusted
for stock dividends, stock splits, combinations and similar events.

     For purposes of this Agreement, "Change of Control" means the occurrence of
any of the following events:

                                      -5-
<PAGE>
 
     (i) Any corporation, person or other entity makes a tender or exchange
offer for any shares of the Company's capital stock, of any class or series,
pursuant to which such corporation, person or other entity acquires or controls
more than 50% of the issued and outstanding shares of the Company's voting stock
(assuming the conversion of all shares of preferred stock convertible into
Common Stock);

     (ii) The stockholders of the Company approve a definitive agreement to
merge or consolidate the Company with or into another corporation or to sell or
otherwise dispose of all or substantially all of the Company's assets, unless
upon the consummation of any such merger or consolidation, the holders of the
Company's securities immediately prior to the consummation of such transaction
hold securities in excess of fifty percent (50%) of the issued and outstanding
voting securities of the surviving or resulting entity (assuming the conversion
of all shares of preferred stock convertible into Common Stock); or

     (iii)  Any person within the meaning of Section 3(a)(9) or Section 13(d)(3)
of the Securities Exchange Act of 1934 acquires more than 50% of the Company's
issued and outstanding voting stock (assuming the conversion of all shares of
preferred stock convertible into Common Stock).

     All options to be granted to the Employee hereunder shall (i) expire ten
years from the date of grant and, in the event of the termination of Employee's
employment with the Company, the portions of such options that are then vested
and exercisable (including any portion that is accelerated pursuant to the above
provisions of this paragraph or other provisions of this Agreement) shall remain
vested and exercisable until ten years after the date of grant, regardless of
the circumstances under which Employee's employment terminates; (ii) be granted
under the Company's 1993 Employee Incentive and Non-Qualified Stock Option Plan
(the "Plan") and shall be subject to the general terms and conditions of the

                                      -6-
<PAGE>
 
Plan; (iii) contain a provision permitting the option exercise price to be paid
by the Employee using any of the payment methods specified in Section 6(b) of
the Plan; and (iv) contain a provision permitting any "incentive stock options"
to be converted to nonqualified stock options by the Employee exercising such
Options after the expiration of any required incentive stock option exercise
period, or otherwise.

     In the event that any of the provisions of this Section 3(b) at anytime
conflict with the provisions of the Plan or any Stock Option Agreement
evidencing the granting of the stock options contemplated by this Section 3(b),
the provisions of this Agreement shall be controlling, and the Company shall use
its best efforts to amend the Plan or such Stock Option Agreement, as necessary,
to conform to this Agreement.

     The Company hereby agrees that, in the event the Company contemplates
completing any equity offerings during the Employment Period, other than in
connection with the private placement of its Series A Convertible Preferred
Stock which is currently in progress, the Board of Directors shall, prior to
such financing, and in any case prior to July 1, 1995, consider granting
additional stock options to the Employee.  The granting of any such stock
options to the Employee shall be based upon the Employee's performance.
Notwithstanding anything contained herein, the Board shall not be under any
obligation to grant the Employee any additional options.

     (c) Employee shall be entitled to participate in all group health and other
insurance programs and all other fringe benefit or retirement plans or other
compensatory plans which the Company may hereafter, in its sole and absolute
discretion, elect to make available to its employees generally on terms no less
favorable than those provided to other employees generally, provided Employee
meets the qualifications therefor, but the Company shall not be

                                      -7-
<PAGE>
 
required to establish any such program or plan, except as provided in this
Section 3.

     (d) Employee shall be entitled to reasonable vacations in accordance with
the then regular procedures of the Company governing executives.

     4.  Expenses  The Company shall pay or reimburse Employee for all
         --------                                                     
reasonable travel and other out-of-pocket expenses necessarily incurred in the
performance of his duties hereunder, upon submission and approval of written
statements and bills in accordance with the then regular procedures of the
Company.

     5.  Representations and Warranties of Employee
         ------------------------------------------

     Employee represents and warrants to the Company that Employee is under no
contractual or other restriction or obligation which is inconsistent with the
execution of this Agreement, the performance of his duties hereunder, or the
other rights of the Company hereunder.

     6.  Non-Competition; Non-Solicitation
         ---------------------------------

     In view of the unique and valuable services it is expected Employee will
render to the Company, Employee's knowledge of the customers, trade secrets, and
other proprietary information relating to the business of the Company and its
customers and suppliers and similar knowledge regarding the Company it is
expected Employee will obtain, and in consideration of the compensation to be
received hereunder, Employee agrees that he will not, during the period he is
employed by the Company under this Agreement or any period of continued
employment by the Company following the expiration of this Agreement, and, if
Employee's employment hereunder is terminated (i) by the Company for cause
pursuant to Section 10(a) hereof or (ii) by Employee other than pursuant to
Section 10(d) hereof, for a period of twelve months after he ceases to be so
employed by the Company, compete with, or be engaged in the same business as,

                                      -8-
<PAGE>
 
or Participate In (as defined below), any other business or commercial entity
(which shall not include a university, hospital, or other non-profit
organization) engaged primarily in the Company's Field of Interest (as defined
below) which during the period he is employed by the Company under this
Agreement or any period of continued employment by the Company following the
expiration of this Agreement competes with, or is engaged in the Company's Field
of Interest, with respect to any product or service sold, or activity engaged in
up to the time of such cessation, in any geographic area in which, at the time
of such cessation, such product or service is sold or activity engaged in by the
Company; provided, however, that the provisions of this Section 6 will not be
deemed breached merely because Employee owns less than 1% of the outstanding
common stock of a corporation in the Company's Field of Interest, if, at the
time of its acquisition by Employee, such stock is listed on a national
securities exchange, is reported on NASDAQ, or is regularly traded in the over-
the-counter market by a member of a national securities exchange; and provided,
further, that the provisions of this Section 6 will not be breached if
Employee's employment with the Company is terminated because the Company becomes
a subject of a proceeding under the Federal Bankruptcy Code, and, subsequent to
such termination, Employee competes with, engages in the same business as, or
Participates In any other business engaged primarily in the Company's Field of
Interest which competes with, intends to compete with, or is engaged in business
in the same Field of Interest as the Company.  The term "Participate In" shall
mean: "directly or indirectly, for his own benefit or for, with, or through any
other person (including Employee's immediate family), firm, or corporation, own,
manage, operate, control, loan money to, or participate in the ownership,
management, operation, or control of, or be connected as a director, officer,
employee, partner, consultant, agent,

                                      -9-
<PAGE>
 
independent contractor, or otherwise with, or acquiesce in the use of his name
in."  The Company's "Field of Interest" means (i) the Company's proposed
products as described in the Company's April 30, 1993 Private Placement
Memorandum, and (ii) any other product (a "New Product") which the Company seeks
to develop or commercialize during the period he is employed by the Company
under this Agreement or any period of continued employment by the Company
following the expiration of this Agreement if (A) more than 10% of the gross
revenues of the Company are derived from any such New Product or group of
related New Products or (B) more than 10% of (x) the Company's research and
development expenses or (y) the Company's total costs and expenses are
associated with any such New Product or group of related New Products.

     Employee agrees that during the period he is employed by the Company under
this Agreement or any period of continued employment by the Company following
the expiration of this Agreement, and for a twelve-month period after he ceases
to be so employed by the Company, he will not directly or indirectly (i) reveal
the name of, interfere with, or endeavor to solicit or entice away from the
Company any of its suppliers, customers, or employees or (ii) employ any person
who was an employee of the Company within a period of one year after such person
leaves the employ of the Company.

     Since a breach of the provisions of this Section 6 could not adequately be
compensated by money damages, the Company shall be entitled, in addition to any
other right and remedy available to it, to an injunction restraining such breach
or a threatened breach, and in either case no bond or other security shall be
required in connection therewith.  Employee agrees that the provisions of this
Section 6 are necessary and reasonable to protect the Company in the conduct of
its business.  If any restriction contained in this Section 6 shall be deemed to
be invalid, illegal, or unenforceable by reason of the extent,

                                      -10-

duration, or geographical scope thereof, or otherwise, then the court making
such determination shall have the right to reduce such extent, duration,
geographical scope, or other provisions hereof, and in its reduced form such
restriction shall then be enforceable in the manner contemplated hereby.

     7.  Patents, etc.
         -------------

     Any interest in patents, patent applications, inventions, technological
innovations, copyrights, copyrightable works, developments, discoveries,

continued employment by the Company following the expiration of this Agreement
in the fields in which the Company may then be engaged or contemplates (as

employed by the Company under this Agreement or any period of continued
employment by the Company following the expiration of this Agreement, and for
one year thereafter utilizing the time, material, facilities, or information of

request of the Company, Employee shall execute all such assignments and other
documents (including applications for patents, copyrights, trademarks, and
assignments thereof) and take all such other action as the Company may
reasonably request in order (a) to vest in the Company all Employee's right,
title, and interest in and to Such Inventions, and (b), if patentable or
copyrightable, to obtain patents or copyrights (including extensions and
renewals) therefor in any and all countries in the name of the Company or any

     8.  Confidential Information
         ------------------------

     During the course of his association with the Company under this Agreement
or otherwise, the Employee shall become privy to "confidential information" of
the Company and others.  As used in this Section 8, "confidential information"
shall mean any information except that information which is generally known by
the Company's principal competitors or which is generally available to the
public, or later becomes public or known by the Company's principal competitors
without the breach by Employee of this Section 8 or shall be known by Employee
other than through his association with the Company or within Employee's
possession prior to being furnished to Employee pursuant to his association with
the Company, and shall include, without limitation, technical data, designs,
software, customer information, business plans, market data, trade secrets or
the like of the Company, whether or not any such document or information is
marked "confidential."   All such confidential information which Employee may
now possess or may obtain or create prior to the end of the period he is
employed by the Company under this Agreement, or of any third party doing
business with the Company (including, without limitation, licensors, licensees,
customers, suppliers and collaborators) shall not be published, disclosed, or
made accessible by him to any other person, firm, or corporation either during
or after the termination of his employment or used by him except during the
Employment Period in the business and for the benefit of the Company, in each
case without prior written permission of the Company.  Employee shall return all
physical evidence of such confidential information to the Company prior to or at
the termination of his employment.

     Employee may disclose any confidential information that is required to be
disclosed by law, government regulation or court order.  If disclosure is
required, Employee shall if reasonably possible give the Company advance notice

                                      -12-
<PAGE>
 
so that the Company may seek a protective order or take other action reasonable
in light of the circumstances.

     9.  Life Insurance
         --------------

     If requested by the Company, Employee shall submit to such physical
examinations and otherwise take such actions and execute and deliver such
documents as may be reasonably necessary to enable the Company, at its expense
and for its own benefit, to obtain life insurance on the life of Employee.
Employee has no reason to believe that his life is not insurable with a
reputable insurance company at rates now prevailing in the City of Boston for
healthy men of his age.

     10.  Termination
          -----------
     (a) Notwithstanding anything to the contrary herein contained, if on or
after the Commencement Date and prior to the end of the term of this Agreement,
either (i) Employee shall be convicted of a crime of moral turpitude or a
felony, (ii) Employee shall engage in willful misconduct or continual neglect in
connection with the performance of his duties hereunder, provided that such
condition remains uncured for a period of twenty days after written notice
describing the same is given to Employee and that isolated and insubstantial
failures shall not constitute "cause" hereunder, (iii) Employee breaches the
material term of Sections 5, 6, 7 or 8 of this Agreement and shall fail to
correct such breach within 20 days after written notice by the Company to
Employee of his commission of the same, then, and in each such case
(constituting "cause"), the Company shall have the right to give written notice
of termination of Employee's services hereunder as of a date (not earlier than
30 days from such notice) to be specified in such notice and the Employment
Period shall terminate on the date so specified, whereupon Employee or his
estate, as the case may be, shall be entitled to receive his compensation at the

                                      -13-
<PAGE>
 
rate then provided pursuant to Section 3(a) hereof earned to the date on which
termination shall take effect, and any other cash and stock bonus, incentive and
performance compensation and awards for or in respect of all prior periods if
not theretofore paid or delivered, and any other benefits, awards or
compensation to which Employee shall have a vested right under the terms of the
agreement, plan or program pursuant to which such benefits were granted.  All
determinations of any such cause for termination pursuant to this Section 10(a)
shall require at least two-thirds vote of the members of the Board of Directors
other than the Employee.

     (b) The Employment Period shall terminate on the date of Employee's death,
or, at the option of the Company, in the event Employee shall be physically or
mentally incapacitated or disabled or otherwise unable substantially to
discharge his duties hereunder for a period of six months, whereupon Employee or
his estate or personal representative, as the case may be, shall be entitled to
receive all his compensation at the rate then provided pursuant to Section 3(a)
hereof (including cash and stock bonuses, incentive and performance compensation
and awards) pro-rated to the date on which termination shall take effect, and
any other benefits, awards or compensation to which Employee shall have a vested
right under the terms of the agreement, plan or program pursuant to which such
benefits were granted.  Notwithstanding such disability, the Company shall
continue to pay Employee all compensation during such six-month period and
through the date of such termination.

     (c) Notwithstanding anything to the contrary herein contained, on or after
any date falling 90 days prior to the first anniversary of the Commencement Date
but prior to the end of the Employment Period, the Company shall have the right
to give written notice of the termination of Employee's services hereunder as of
a date (not earlier than 90 days from such notice) to

                                      -14-
<PAGE>
 
be specified in such notice and the Employment Period shall terminate on the
date so specified.  In the event that the Company terminates the Employment
Period pursuant to this subsection 10(c) or this Agreement shall not be renewed
upon the expiration hereof, then in either such case (i) except as otherwise
provided in Section 11 below, the Company shall pay to the Employee, upon such
termination, a lump sum cash amount equal to the product of (x) the Employee's
monthly salary at the rate in effect on the date that written notice of
termination is given by the Company multiplied by (y) nine; and (ii) the Company
shall continue to be responsible for paying the cost of any medical insurance
benefits then provided to or for the benefit of Employee or his family at the
Company's expense, until the earlier of (x) nine months from the date of
termination of Employee's employment, and (y) the date on which Employee
commences full-time employment with another employer, (iii) all cash and stock
bonus, incentive and performance compensation and awards for or in respect of
all prior periods if not theretofore paid or delivered shall be paid or
delivered to Employee, and all cash and stock bonus, incentive and performance
compensation and awards in respect of the then current period shall be pro-rated
to the date on which such termination shall take effect, (iv) the vesting of the
options referred to in Section 3 above shall accelerate as provided in Section
3(b) above, and (v) the Company shall pay to or deliver to Employee any other
benefits, awards or compensation to which Employee shall have a vested right
under the terms of the agreement, plan or program pursuant to which such
benefits were granted.

     (d) Employee may terminate this Agreement on not less than 60 days' prior
written notice to the Company if any one or more of the following shall occur:

                                      -15-
<PAGE>
 
     (1) material diminution of Employee's duties and authority by the Company,
without the Employee's prior consent, and such duties and authority are not
restored for twenty days after written notice of such action is given by
Employee to the Company and that isolated and insubstantial changes in
Employee's duties and responsibilities shall not give rise to any such right of
termination;

     (2) a material breach of the terms of this Agreement by the Company or any
other material agreement with Employee (including without limitation failure to
pay or deliver compensation or other material amounts due hereunder) and such
breach continues uncured for twenty days after written notice of such breach is
first given by Employee to the Company;

     (3) a Change in Control occurs; provided, that Employee gives notice of
termination within 90 days after such occurrence; or

     (4) Employee is not continuously a member of the Board of Directors and the
President and Chief Executive Officer of the Company during the term of this
Agreement; Employee is not the highest ranking executive officer of the Company
with the power, subject to the direction of the Board of Directors, to appoint
and remove all other employees of the Company; the retention of any senior
executive officer by the Company, or an offer to pay compensation to any senior
executive of the Company that in either case is unacceptable to Employee, in his
reasonable judgment; provided that Employee gives written notice of termination
to the company within twenty days after such occurrence and such prohibited
event is not remedied within twenty days of such notice.

     In the event of such termination by Employee, then Employee shall be
entitled to receive (in addition to all other remedies, damages or relief to
which he might otherwise be entitled by law, in equity or otherwise),

                                      -16-
<PAGE>
 
all amounts which would have been payable or deliverable under Section 10(c) had
Employee's employment been terminated by the Company without cause.

     11.  Merger, etc.
          ------------

     In the event of a future disposition of (or including) the properties and
business of the Company, substantially as an entirety, by merger, consolidation,
sale of assets or otherwise (unless upon the consummation of any such merger or
consolidation, the holders of the Company's securities immediately prior to the
consummation of such transaction hold more than fifty percent (50%) of the
issued and outstanding voting securities of the surviving or resulting entity
(assuming the conversion of all shares of preferred stock convertible into
Common Stock), then the Company may elect, subject to Employee's right to
terminate pursuant to Section 10(d) above, to assign this Agreement and all of
its rights and obligations hereunder to the acquiring or surviving entity;
provided, that Employee consents in writing to such assignment.  Any such
consent by Employee may include, among others, the following conditions:  (i)
that such entity shall assume in writing all of the obligations of the Company
hereunder; (ii) that the Company (in the event and so long as it remains in
existence) shall remain liable for the performance of its obligations hereunder
in the event of a breach by the acquiring entity of this Agreement; and (iii)
assurance satisfactory to Employee that he will be able to continue to have or
receive the benefits comparable to those to be afforded to him hereunder,
including without limitation, provisions with respect to his status and office
with the Company and his salary and other forms of compensation, from the
acquiring or surviving entity, and for such purposes all of the options granted
to Employee shall survive any such transaction, whether or not vested, and shall
be exchanged for comparable options expiring not later than ten years from the
original date of grant, to purchase shares of the

                                      -17-
<PAGE>
 
acquiring or surviving entity.  In the event that the Company or any such
successor elects to terminate this Agreement pursuant to Section 10(c) hereof in
connection with, or after the consummation of, any such disposition, the amount
of the payment due under said Section 10(c)(i) shall be equal to the product of
(x) the Employee's monthly salary at the rate in effect on the date that written
notice of termination is given by the Company or such successor, multiplied by
(y) twelve.

     12.  Indemnification.
          --------------- 

     The Company shall indemnify Employee, to the maximum extent permitted by
applicable law, against all costs, charges and expenses incurred or sustained by
him in connection with any action, suit or proceeding to which he may be made a
party by reason of being an officer, director or employee of the Company or of
any subsidiary of the Company if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
Company, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.

     13.  Excise Tax.
          ---------- 

     If any payments made to or in respect of this Agreement, or otherwise in
respect of his employment by the Company, become subject to the excise tax
described in Internal Revenue Code 4999, the Company shall make a special loan
(the "Loan") to him sufficient, on an after-tax basis (taking into account
federal, state and local taxes and related interest and penalties), to pay 50%
of such excise taxes.  The Loan shall be secured by, and the Company shall have
recourse only to, the Common Stock owned by Employee (including Common Stock
underlying stock options) and shall be due 10 years from the date made;
provided, however, that upon each sale of shares of Common Stock an amount equal
to 50% of the proceeds of such sale in excess of Employee's basis in such

                                      -18-
<PAGE>
 
shares shall be applied to reduce the principal amount of the Loan.  The Loan
shall be interest free.  Employee shall cooperate with the Company to enable the
Company to perfect the security interest referred to herein.

     14.  No Mitigation.
          ------------- 

     Employee shall not be required to mitigate the amount of any payment
provided for hereunder by seeking other employment or otherwise, nor shall the
amount of any payment provided for hereunder be reduced by any compensation
earned by Employee as the result of employment by another employer after the
date of termination of his employment by the Company.

     15.  Legal Costs.
          ----------- 

     If Employee institutes any legal action to enforce his rights under, or to
recover damages for breach of, this Agreement, and Employee prevails, he shall
be entitled to recover from the Company any actual expenses for fees and
disbursements of attorneys, accountants and other professionals incurred by him.
If any payment made to or in respect of Employee pursuant to this Section 15
becomes subject to any tax, the Company shall make a special payment to him
sufficient, on an after-tax basis (taking into account federal, state and local
taxes and related interest and penalties), to put him in the same position as
would have been the case had such taxes been applicable to any payments or
benefits provided in this subsection.

     16.  Survival
          --------

     The covenants, agreements, representations and warranties of the Employee
and the Company contained in or made pursuant to this Agreement shall survive
Employee's termination of employment as provided herein.

     17.  Entire Agreement; Modification
          ------------------------------

     This Agreement sets forth the entire understanding of the parties with
respect to the subject matter hereof, supersedes all existing agreements

notice changing a party's address which shall be deemed given at the time of
receipt thereof.

     19.  Waiver
          ------

     Any waiver by either party of a breach of any provision of this Agreement
shall not operate as or be construed to be a waiver of any other breach of such
provision or of any breach of any other provision of this Agreement.  The
failure of a party to insist upon strict adherence to any term of this Agreement
on one or more occasions shall not be considered a waiver or deprive that party
of the right thereafter to insist upon strict adherence to that term or any
other term of this Agreement.  Any waiver must be in writing, signed by the
party giving such waiver.

     20.  Binding Effect
          --------------

                                      -20-

          ------ 

     In the event that any term or provision of this Agreement shall be deemed
by a court of competent jurisdiction, arbitrator or mediator, as the case may
be, to be overly broad in scope, duration or area of applicability, the court,
arbitrator or mediator, as the case may be, considering the same shall have the
power and hereby is authorized and directed to modify such term or provision to
limit such scope, duration or area, or all of them, so that such term or

or, at the direction of the Company, any present or future parent, subsidiary,
or affiliate of the Company, and (subject to Section 10) any successor or assign
of any of them (the "Corporations"), and Employee desires to perform such
services, on the terms and conditions hereinafter set forth.

     1.  Term

     The Company agrees to employ Employee, and Employee agrees to serve, on the

hereunder, Employee shall be available for reasonable travel as the needs of the
business require.

     (b) The Company acknowledges that the Employee is currently employed by
Cerner Corporation ("Cerner") and that the Employee desires to facilitate an

     (c) Subject to any business travel reasonably required in connection with
the performance by the Employee of his obligations hereunder, the Employee will
perform his services hereunder in the Boston metropolitan area, for a period of
not less than two years from the commencement of the Employment Period.  In the
event that the Company requires that the Employee relocate outside of the Boston

the Employee shall have the right to refuse to so relocate, and in such event
this Agreement shall be deemed terminated pursuant to Section 9(c) below, and
the Employee shall receive the severance benefits described in Section 9(c)

<PAGE>
 
end of the second year of the Employment Period, the Employee shall be obligated
to so relocate; provided, that the Company agrees to reimburse the Employee for
his reasonable out of pocket expenses incurred in connection with such

     3.  Compensation; Benefits

     (a) As compensation for his services hereunder, the Company shall pay
Employee, during the Employment Period, a salary payable monthly at the rate of

of such annual bonuses based upon the number of weeks during such calendar year
that the Employee was employed.  The Company shall review the Employee's
performance and the performance of the Company annually, and the Employee's
Salary may be increased, at the discretion of the Company, on the basis of such

generally for its senior executive employees.  Employee acknowledges that the
Company shall be entitled, in its sole and absolute discretion, to change or

so long as at all times the Company provides Employee with group health and
hospitalization insurance.

     (e) Employee shall be entitled to reasonable vacations in accordance with
the then regular procedures of the Company governing executives; provided,
however, that the Employee shall be entitled to not less than three weeks

that, if so requested by the Company, the Employee shall limit the amount of
vacation time taken by the Employee during the first two years of the Employment
Period to two weeks in the first year and three weeks in the second year;
provided, that in any such case the Employee shall be entitled to accrue

                                      -5-
<PAGE>
 
such unused vacation time, and such accrued vacation time may be taken at

     Employee shall be entitled to reimbursement for reasonable travel and other

     Employee represents and warrants to the Company that his performance of the
terms of this Agreement and as an employee of the Company does not and will not
breach any agreement or obligation to which the Employee is a party or by which
he is bound.

     6.  Non-Competition; Non-Solicitation

     In view of the unique and valuable services it is expected Employee will
render to the Company, Employee's knowledge of the customers, trade secrets, and
other proprietary information relating to the business of the Company and its
customers and suppliers and similar knowledge regarding the Company it is
expected Employee will obtain, and in consideration of the compensation to be
received hereunder, Employee agrees that he will not, during the period he is
employed by the Company under this Agreement or otherwise, and for a period of
eighteen months after he ceases to be employed by the Company under this
Agreement or otherwise, compete with, intend to compete with, or be engaged in
the same business as, or Participate In (as defined below), any other business
or organization (which shall not include a university, hospital, or other non-
profit organization) which during the period he is employed by the Company under
this Agreement or otherwise, and for such eighteen-month period thereafter
competes with, intends to compete with, or is engaged in the same

                                      -6-
<PAGE>
 
business as the Company, with respect to (i) any product or service in the
cardiovascular field sold or actively being developed by the Company up to the
time of such cessation in any geographic area in which, at the time of such
cessation, such product or service is sold or activity engaged in or (ii) any
product or service in any other field sold or actively being developed by the
Company at the time of such cessation with respect to which Employee acquires
"confidential information" (as hereinafter defined) and provides direct
assistance during the course of his employment hereunder or otherwise with the
Company; provided, however, that the provisions of this Section 6 will not be
deemed breached merely because (x) Employee is employed by a business or
organization which competes with or is engaged in the same business as the
Company, with respect to any product or service, if (A) such other business or
organization derives less than 25% of its revenues from such competitive
activities and (B) the Employee is employed by such other business or
organization in a capacity which does not result in his direct or indirect
involvement with such competitive activities; or (y) Employee owns less than 1%
of the outstanding common stock of a corporation, if, at the time of its
acquisition by Employee, such stock is listed on a national securities exchange,
is reported on NASDAQ, or is regularly traded in the over-the-counter market by
a member of a national securities exchange; and provided, further, that the
provisions of this Section 6 will not be breached if Employee's employment with
the Company is terminated because the Company becomes a subject of a proceeding
under the Federal Bankruptcy Code, and, subsequent to such termination, Employee
competes with, engages in the same business as, or Participates In any other
business which competes with or is engaged in the same business as the Company.
The term "Participate In" shall mean: "directly or indirectly, for his own
benefit or for, with, or through any other person (including Employee's

                                      -7-
<PAGE>
 
immediate family), firm, or corporation, own, manage, operate, control, loan
money to, or participate in the ownership, management, operation, or control of,
or be connected as a director, officer, employee, partner, consultant, agent,
independent contractor, or otherwise with, or acquiesce in the use of his name
in."

     Employee agrees that during the period he is employed by the Company under
this Agreement or otherwise, and for an eighteen-month period after he ceases to
be so employed by the Company, he will not directly or indirectly (i) reveal the
name of, solicit or interfere with, or endeavor to entice away from the Company
any of its suppliers, customers, or employees or (ii) employ any person who was
an employee of the Company within a period of one year after such person leaves
the employ of the Company.

     Since a breach of the provisions of this Section 6 could not adequately be
compensated by money damages, the Company shall be entitled, in addition to any
other right and remedy available to it, to seek an injunction restraining such
breach or a threatened breach.  In either case no bond or other security shall
be required in connection therewith.  Employee agrees that the provisions of
this Section 6 are necessary and reasonable to protect the Company in the
conduct of its business.  If any restriction contained in this Section 6 shall
be deemed to be invalid, illegal, or unenforceable by reason of the extent,
duration, or geographical scope thereof, or otherwise, then the court making
such determination shall have the right to reduce such extent, duration,
geographical scope, or other provisions hereof, and in its reduced form such
restriction shall then be enforceable in the manner contemplated hereby.

     7.  Patents, etc.

     Any interest in patents, patent applications, inventions, technological
innovations, copyrights, copyrightable works, developments,

                                      -8-
<PAGE>
 
discoveries, designs, and processes which Employee during the period he is
employed by the Company under this Agreement or otherwise and for one year
thereafter may acquire rights to, conceive of, or develop and which (i) relate
to the cardiovascular field or any other field with respect to which the
Employee has provided direct assistance to the Company in connection with any
product or service sold or actively engaged by the Company in such field, or
(ii) are developed utilizing the time, material, facilities, or information of
the Company ("Such Inventions") shall belong to the Company; as soon as Employee
owns, conceives of, or develops any Such Invention, he agrees immediately to
communicate such fact in writing to the Secretary of the Company, and without
further compensation, but at the Company's expense (except as noted in clause
(a) of this Section 7), forthwith upon request of the Company, Employee shall
execute all such assignments and other documents (including applications for
patents, copyrights, trademarks, and assignments thereof) and take all such
other action as the Company may reasonably request in order (a) to vest in the
Company all Employee's right, title, and interest in and to Such Inventions,
free and clear of liens, mortgages, security interests, pledges, charges, and
encumbrances arising from the acts of Employee ("Liens") (Employee to take such
action, at his expense, as is necessary to remove all such Liens) and (b), if
patentable or copyrightable, to obtain patents or copyrights (including
extensions and renewals) therefor in any and all countries in such name as the
Company shall determine.

     8.  Confidential Information

     All confidential information which Employee has obtained prior to the
execution of this Agreement from the Company, may obtain during or after the

the Company prior to or at the termination of his employment.  As used in this
Section 8, "confidential information" shall mean any information except that
information which is generally known by the Company's principal competitors or
which is generally available to the public, or later becomes public without a
breach by Employee of this Section 8, or is already known by the Employee and
has not been obtained or learned by the Employee from the Company or from a
third party as a result of a breach of any obligation of confidentiality owed by
such third party to the Company.

     (a) Notwithstanding anything to the contrary herein contained, if on or

services hereunder as of a date (not earlier than 30 days from such notice) to
be specified in such notice and the Employment Period shall terminate on the
date so specified.

     (b) In the event that Employee shall die prior to the end of the Employment

     10.  Merger, etc.

     In the event of a future disposition of (or including) the properties and
business of the Company, substantially as an entirety, by merger, consolidation,
sale of assets or otherwise, then the Company may elect:

     (a) to assign this Agreement and all of its rights and obligations
hereunder to the acquiring or surviving entity; provided that such entity shall
assume in writing all of the obligations of the Company hereunder; and provided,
further, that the Company (in the event and so long as it remains in existence)
shall remain liable for the performance of its obligations hereunder in the
event of a breach by the acquiring entity of this Agreement; or

     (b) in addition to its other rights of termination, the Company shall have

contained in or made pursuant to this Agreement shall survive Employee's
termination of employment as provided herein.

     12.  Entire Agreement; Modification

respect to the subject matter hereof, supersedes all existing agreements

                                      -12-

Employee shall be sufficient if addressed to Employee as provided in this
Section 13.  Any notice or other communication given by certified mail shall be
deemed given three days after the time of certification thereof, except for a
notice changing a party's address which shall be deemed given at the time of

     14.  Waiver

     Any waiver by either party of a breach of any provision of this Agreement
shall not operate as or be construed to be a waiver of any other breach of such
provision or of any breach of any other provision of this Agreement.  The
failure of a party to insist upon strict adherence to any term of this Agreement
on one or more occasions shall not be considered a waiver or deprive that party
of the right thereafter to insist upon strict adherence to that term or any
other term of this Agreement.  Any waiver must be in writing, signed by the
party giving such waiver.

     15.  Binding Effect

     Employee's rights and obligations under this Agreement shall not be

rights enforceable by any Person not a party to this Agreement (except as
provided in Section 15).

     17.  Headings

     The headings in this Agreement are solely for the convenience of reference
and shall be given no effect in the construction or interpretation of this
Agreement.

     18.  Remedy

     In the event that any term or provision of this Agreement shall be deemed
by a court of competent jurisdiction, arbitrator or mediator, as the case may
be, to be overly broad in scope, duration or area of applicability, the court,
arbitrator or mediator, as the case may be, considering the same shall have the
power and hereby is authorized and directed to modify such term or provision to
limit such scope, duration or area, or all of them, so that such term or
provision is no longer overly broad and to enforce the same as so limited.
Subject to the foregoing sentence, in the event that any provision of this
Agreement shall be held to be invalid or unenforceable for any reason, such
invalidity or unenforceability shall attach only to such provision and shall not
affect or render invalid or unenforceable any other provision of this Agreement.

     19.  Counterparts; Governing Law

     This Agreement may be executed in any number of counterparts, each of which
shall be deemed an original, but all of which together shall constitute

                                      -14-
<PAGE>
 
one and the same instrument. It shall be governed by and construed in accordance
with the laws of the State of Delaware, without giving effect to principles of
conflicts of laws.

     IN WITNESS WHEREOF, the parties have duly executed this Agreement as of the
date first above written.

                           STANDARD COMMERCIAL LEASE
1. Identification

   The Lease made as of May     , 1995 by and between R. W. CONNELLY (the
                             ---
   "Landlord"), having an address at 57 Bedford Street, Suite 100, Lexington,
   Massachusetts  02173, and  CAMBRIDGE HEART, INC., a Massachusetts corporation
   (the "Tenant"), having an address at 99 South Bedford Street, Suite 204,
   Burlington, Massachusetts  01803.


2. Premises

   Tenant,  which expression shall include its successors, executors,
   administrators, and assigns where the context so admits, and hereby leases
   the following described premises:   Approximately 11,000 square feet of floor
   area on the first floor situated in a certain building known as One Oak Park
   Drive, in the Town of Bedford, Middlesex County, Massachusetts, as more
   particularly described in Exhibit A, together with the right to use Common,
   with others entitled thereto, the hallways and stairways necessary for access
   to said leased premises and lavatories nearest thereto.


3. Term

   The term of this lease shall commence on the later of   (i)  June 1, 1995, or
   (ii) the date the Landlord's Work is Substantially Complete (the "Term
   Commencement Date") and shall expire, unless earlier extended or terminated
   in accordance with the terms hereof, at midnight on the last day of the
   sixtieth (60th) full calendar month following the Term Commencement Date;
   unless earlier terminated under an Early Termination Option which allows the
   Tenant a one-time right to terminate the Lease at the end of the fourth year
   by providing no less than six (6) months prior written notice and a payment
   of twenty-two thousand ($22,000) dollars with the notice.


4. Rent

   Thousand Dollars ($88,000) in year one and One Hundred Four Thousand Five
   Hundred Dollars ($104,500) in years 2 - 5, payable in advance in monthly
   installments of $7,333.33 and $8,708.33, respectively.


5. Rent Adjustment

   Additional Basic Rent

   The Landlord represents that the Taxes on the building for Fiscal Year 1995
   are $1.25 per total rentable square foot (currently 22,000 square feet).  In
   the event of any increase in Taxes for any subsequent Fiscal Year exceed
   $1.25 per rentable square foot,
<PAGE>
 
   then Landlord shall notify Tenant of such increase and Tenant agrees to pay
   to Landlord the amount which the Taxes exceed $1.25 per rentable square foot
   for the leased premise.  Such payment will be made to Landlord 30 days after
   such notice.

   If Common Expenses for the Period June 1, 1995 through May 31, 1996 (or each
   subsequent annual period) exceeds $2.50 per rentable square foot then the
   Landlord may notify Tenant and Tenant agrees to pay any such increase in
   excess of $2.50 per rentable square foot.  Such payment will be made to
   Landlord within 30 days after such notice.   The increase in operating
   expenses shall not increase by more than the Consumer Price Index for All
   Urban Consumers (CPI-U), Boston, Massachusetts, with the commencement month
   and year being the base from $2.50 per rentable square foot.

   "Common Expenses" shall mean any and all reasonable charges, costs and
   expenses of every kind and nature whatever which the Landlord may from time
   to time actually incur and the reasonable value, based on competitive rates,
   of any materials and services which the Landlord may provide in good faith
   with respect to the operation and maintenance of the Building and the
   Property, including, without limitation,   (i)  making repairs to and
   undertaking maintenance of the Building and the Property;   (ii)  providing
   utilities, including heat, water, sewer, air conditioning and ventilation as
   provided in Paragraph 7 hereof, to the Premises and to the common areas of

   providing watering, landscaping and lawn care for the Property;  (v)
   sanding, plowing and removal of snow and ice from the driveways, walkways and
   parking areas;  (vi)  maintaining casualty and liability insurance with
   respect to the Landlord, the Premises, the Building and the Property; and
   (vii)  reasonable administrative costs of the Landlord, not to exceed 5%
   gross income which shall be commensurate with those normally charged for
   suburban office buildings of this nature in the metropolitan Boston area.
   Common Expenses shall not include capital costs, mortgage debt service,
   ground rent, and legal compliance.  "Taxes" shall mean any and all real
   estate taxes, betterments and special assessments or amounts in lieu or in
   the nature thereof which may now or hereafter be levied upon the Building or
   Property.

   Notwithstanding the foregoing, during the Term the Tenant shall pay on an
   annual basis the Tenant's percentage only if the amount by which Common
   Expenses for the Building or Property exceed two dollars and fifty cents
   ($2.50) per rentable square foot.

   If any payment of Basic Rent or Additional Rent is not paid to the Landlord
   within five days of its due date or within any applicable grace period, then
   at the Landlord's option, without notice and in addition to all other
   remedies hereunder, the Tenant shall pay upon demand to the Landlord as
   Additional Rent interest thereon at an annual rate equal to the corporate
   rate of the Bank of Boston from time to time in effect plus two (2) percent,
   such interest to be computed from the date such Basic Rent or Additional Rent
   was originally due through the date when paid in full.

   Upon written notice from Tenant, the Landlord shall provide copies of
   documentation reasonably evidencing the costs incurred by the Landlord as
   Common Expenses and Taxes.  The Landlord shall be obligated to provide such
   written summary and documentation only if Common Expenses exceed two dollars
   and fifty cents ($2.50) per

                                       2
<PAGE>
 
   rentable square foot and Taxes exceed one dollar and twenty-five cents
   ($1.25) per rentable square foot.

   Common Expenses shall exclude cost of repairs and general maintenance paid by
   proceeds of insurance or by Tenant or other third parties and alteration
   attributable solely to tenants of the building other than Tenant.  The net
   amount of any abatement shall be deducted from the Real Estate taxes.


6. Security Deposit

   Upon the execution of this lease, the Tenant shall pay to the Landlord the
   amount of   $8,479.17, which shall be held as a security for the Tenant's
   performance as herein provided and refunded to the Tenant at the end of this
   lease subject to the Tenant's  satisfactory compliance with the conditions
   hereof.


7. Utilities

   The Tenant shall pay, as they become due, all bills for electricity (which
   includes heat and air conditioning) that are presently separately metered.
   The Landlord agrees to provide all other utility service and to furnish

   obtain materials, fire or other casualty and from any causes beyond the
   commercially reasonable control of the Landlord;  (iii) and any delays caused
   by Tenant's failure to deliver a signed Lease by April 28, 1995.

   workmanlike manner using first-class materials and in compliance with all
   applicable laws, by-laws, ordinance, codes, rules, regulation orders and

   acknowledge and agree that Tenant's use and operation of the Leased premises
   for the intended use shall be deemed not to violate the provision of this

    occupancy as provided herein. Notwithstanding the foregoing Landlord's
    consent shall not be required for minor alterations. However, Landlord may
    ask that

    reasonably satisfactory to Tenant from the holders of any such instrument

    to others, and at any time within six (6) months before the expiration of
    the term, may affix to any suitable part of the leased premises a notice for
    letting or selling the leased premises or property of which the leased
    premises are a part and keep the same so affixed without hindrance or

    omission on the part of the Tenant or any of its agents, employees,
    subtenants, licensees, invitees or assignees. The Tenant further agrees to

    reasonable attorneys' fees) and other liabilities incurred in connection
    with any such indemnified claim or action or proceeding brought thereon, any

19. Fire Casualty -- Eminent Domain

    Should a substantial portion of the leased premises, or of the property of
    which they are a part, be substantially damaged by fire or other casualty,
    or be taken by eminent domain, the Landlord may elect to terminate this
    lease. When such fire, casualty, or taking renders the leased premises
    substantially unsuitable for their intended use, a just and proportionate
    abatement of rent shall be made, and the Tenant may elect to terminate this
    lease if:

    (a) The  Landlord  fails to give written notice within thirty (30) days of
        intention to restore leased premises, or

    (b) The  Landlord  fails to restore the leased premises to a condition
        substantially equivalent to previous conditions within ninety (90) days
        of said fire, casualty or taking.

    which the  Tenant may have for damages or injury to the leased premises for
    any taking by eminent domain, except for damage to the  Tenant's  fixtures,
    property, or equipment.

20. Default and Bankruptcy

    In the event that:

    (a) The  Tenant shall default in the payment of any installment of rent or
        other sum herein specified and such default shall continue for ten (10)
        days after written notice thereof; or

    (b) The Tenant shall default in the observance or performance of any other
        of the  Tenant's  covenants, agreements, or obligations hereunder and
        such default shall not be corrected within thirty (30) days after
        written notice thereof; or

    (c) The Tenant shall be declared bankrupt or insolvent according to law, or,
        if any assignment shall be made of  Tenant's  property for the benefit
        of creditors,

    then the Landlord shall have the right thereafter, while such default
    continues, to re-enter and take complete possession of the leased premises,
    to declare the term of this lease ended, and remove the Tenant's effects,
    without prejudice to any remedies which might be otherwise used for arrears
    of rent or other default. The Tenant shall indemnify the Landlord against
    all loss of rent and other payments which the Landlord may incur by reason
    of such termination during the residue of the term. If the Tenant shall
    default, after reasonable notice thereof, in the observance or performance
    of any conditions or covenants on Tenant's part to be observed or performed
    under or by virtue of any of the provisions in any article of this lease,
    the Landlord, without being under any obligation to do so and without
    thereby waiving such default, may remedy such default for the account and at
    the expense of the Tenant. If the Landlord makes any expenditures or incurs
    any obligations for the payment of money in connection therewith, including
    but not limited to, reasonable attorney's fees in instituting, prosecuting
    or defending any action or proceeding, such sums paid or obligations
    insured, with interest at the rate of P + 3 per cent per annum and costs,
    shall be paid to the Landlord by the Tenant as additional rent.

          period.


     2.4  At the end of the exclusive period, the license granted hereunder
shall become nonexclusive and shall extend to the end of the term or terms for

subsequent periods.

     4.3  No multiple royalties shall be payable because any LICENSED PRODUCT,
its manufacture, use, lease or sale are or shall be covered by more than one
PATENT RIGHTS patent application or PATENT RIGHTS patent licensed under this
Agreement. If a given product is covered by more than one LICENSE AGREEMENT,
then the total royalty paid to M.I.T. on such product shall not exceed the
maximum royalty applicable under any single LICENSE AGREEMENT.

following the end of the calendar year to which they pertain, to the inspection
of M.I.T. or its agents for the purpose of verifying LICENSEE's royalty

inspection lead to the discovery of a greater than ten percent (10%) discrepancy
in reporting, LICENSEE agrees to pay half the cost of such inspection.

     5.2  LICENSEE, within sixty (60) days after December 31, of each year,
shall deliver to M.I.T. true and accurate reports, giving such particulars of

the term of this Agreement the PATENT RIGHTS in the United States and in the
foreign countries listed in Appendix AMES-B hereto. Appendix AMES-B may be
amended by verbal agreement of both parties, such agreement to be confirmed in
writing within ten (10) days. The prosecution, filing and maintenance of all
PATENT RIGHTS patents and applications shall be the primary responsibility of
M.I.T.; provided, however, LICENSEE shall have reasonable opportunities to
advise M.I.T. and shall cooperate with M.I.T. in such prosecution, filing and
maintenance of all patents and applications included within the PATENT RIGHTS.

     6.2  Payment of all fees and costs relating to the filing, prosecution, and
maintenance of the PATENT RIGHTS shall be the responsibility of LICENSEE,
whether such fees and costs were incurred before or after the date of this
Agreement. LICENSEE shall have the right to approve the attorney selected by
M.I.T. LICENSEE may elect to discontinue all or a portion of the prosecution of
the PATENT RIGHTS, provided that LICENSEE gives M.I.T. reasonable notice, so
that M.I.T. may, at its own expense, elect to preserve those rights.

                            ARTICLE 7 - INFRINGEMENT
                            -----------------------

     7.1  Each party shall inform the other party promptly in writing of any
alleged infringement of the PATENT RIGHTS by a third party and of any available
evidence thereof.

     7.2  During the term of exclusivity of this Agreement, LICENSEE shall have
the right, but shall not be obligated, to prosecute at its own expense all
infringements of the PATENT RIGHTS and, in furtherance of such right, M.I.T.
hereby agrees that LICENSEE may include M.I.T. as a party plaintiff in any such
suit, without expense to M.I.T.. The total cost of any such infringement action
commenced or defended solely by LICENSEE shall be borne by LICENSEE and LICENSEE
shall keep any recovery or damages for past infringement derived therefrom.

     7.3  If within six (6) months after having been notified of any alleged
infringement, LICENSEE shall have been unsuccessful in persuading the alleged
infringer to desist and shall not have brought and shall not be diligently
prosecuting an infringement action, or if LICENSEE shall notify M.I.T. at any
time prior thereto of its intention not to bring suit against any alleged
infringer then, and in those events only, M.I.T. shall have the right, but shall
not be obligated, to prosecute at its own expense any infringement of the PATENT
RIGHTS and M.I.T. may, for such purposes, use the name of LICENSEE as party
plaintiff. No settlement, consent judgment or other voluntary final disposition
of the suit may be entered into without the consent of M.I.T. and LICENSEE,
which consent shall not unreasonably be withheld.

     7.4  In the event that LICENSEE shall undertake the enforcement and/or
defense of the PATENT RIGHTS by litigation, LICENSEE may withhold up to fifty
percent (50%) of the payments otherwise thereafter due M.I.T. under Article 4
hereunder and apply the same toward reimbursement of up to half of LICENSEE's
expenses, including reasonable attorneys' fees, in connection therewith. Any
recovery of damages by LICENSEE for each such suit shall be applied first in
satisfaction of any unreimbursed expenses and legal fees of LICENSEE relating to
such suit, and next toward reimbursement of M.I.T. for any payments under
Article 4 past due or withheld and applied pursuant to this Article 7. The
balance remaining from any such recovery shall be divided so that the fraction
of the recovery due M.I.T. is calculated by creating a fraction, the numerator
of which is the amount of royalties withheld, and the denominator of which is
the cost of litigation paid by LICENSEE, but in no event shall such sum be less
than Twelve Percent (12%) of the net recovery.

     7.5  In the event that a declaratory judgment action alleging invalidity or

     8.4  M.I.T. hereby represents and warrants, to the best of its knowledge
and belief, to LICENSEE that the execution, delivery and performance of this
Agreement by M.I.T. does not, and will not, violate any commitments or

regulations controlling the export of technical data, computer software,
laboratory prototypes and other commodities (including the Arms Export Control
Act, as amended and the Export Administration Act of 1979), and that its
obligations hereunder are contingent on compliance with applicable United States

commodities may require a license from the cognizant agency of the United States
Government and/or written assurances by LICENSEE that LICENSEE shall not export
data or commodities to certain foreign countries without prior approval of such
agency. M.I.T. neither represents that a license shall not be required nor that,
if required, it shall be issued.

written consent obtained from M.I.T., or said employee, in each case, except
that LICENSEE may state that it is licensed by M.I.T. under one or more of the
patents and/or applications comprising the PATENT RIGHTS. Such statements may
appear in the Private Placement Memoranda to be circulated by KBL Healthcare,
Inc., or in filings in compliance with securities laws. LICENSEE shall not use
the names or trademarks of the Massachusetts Institute of Technology, nor any
adaptation thereof, nor the names of any of its employees to imply that M.I.T.
endorses the LICENSED PRODUCTS sold by LICENSEE.


                            ARTICLE 11 - ASSIGNMENT
                            -----------------------

reasonable detail the nature of such dispute. By not later than five (5)
business days after the recipient has received such notice of dispute, each
party shall have selected for itself a representative who shall have the
authority to bind such party, and shall additionally have advised the other
party in writing of the name and title of such representative. By not later than
ten (10) business days after the date of such notice of dispute, such
representatives shall schedule a date for a mediation hearing with the Cambridge
Dispute Settlement Center or Endispute Inc. in Cambridge, Massachusetts. If the
representatives of the parties have not been able to resolve the dispute within
fifteen (15) business days after such mediation hearing, the parties shall have
the right to pursue any other remedies legally available to resolve such dispute
in either the Courts of the Commonwealth of Massachusetts or in the United
States District Court for the District of Massachusetts, to whose jurisdiction
for such purposes M.I.T. and LICENSEE each hereby irrevocably consents and

activities as a University Professor at M.I.T., M.I.T. will approach LICENSEE in
good faith to negotiate a reasonable resolution.

     12.3  Notwithstanding the foregoing, nothing in this Article shall be
construed to waive any rights or timely performance of any obligations existing
under this Agreement.

thereof may, however, after the effective date of such termination, sell all
LICENSED PRODUCTS; and complete LICENSED PRODUCTS in the process of manufacture
at the time of such termination and sell the same, provided that LICENSEE shall

of LICENSED PRODUCTS.

     13.6  Upon termination of this Agreement for any reason, any sublicensee
not then in default shall have the right to seek a license from M.I.T. M.I.T.
agrees to negotiate such licenses in good faith under reasonable terms and
conditions.

          a LICENSED PRODUCT; or

     (b)  the expiration of fifteen (15) years after the EFFECTIVE DATE of this
          Agreement; provided, however, that if an application for premarket

     2.4  At the end of the exclusive period, the license granted hereunder
shall become nonexclusive and shall extend to the end of the term or terms for

          development of the LICENSED PRODUCTS and LICENSED PROCESSES in the

to Paragraph 13.3 hereof.

     3.5  If LICENSEE has diligently been pursuing the FDA approval required to
sell LICENSED PRODUCTS or products utilizing LICENSED PROCESSES on the
commercial market, and can demonstrate such diligence to M.I.T. by means of

following the end of the calendar year to which they pertain, to the inspection
of M.I.T. or its agents for the purpose of verifying LICENSEE's royalty

inspection lead to the discovery of a greater than ten percent (10%) discrepancy
in reporting, LICENSEE agrees to pay the full cost of such inspection.

     5.2  LICENSEE, within sixty (60) days after December 31, of each year,
shall deliver to M.I.T. true and accurate reports, giving such particulars of

LICENSEE's fiscal year, LICENSEE shall provide M.I.T. with LICENSEE's certified
financial statements for the preceding fiscal year including, at a minimum, a
Balance Sheet and an Operating Statement.

     5.5  The royalty payments set forth in this Agreement and amounts due under
Article 6 shall, if overdue, bear interest until payment at a per annum rate two
percent (2%) above the prime rate in effect at the Chase Manhattan Bank (N.A.)
on the due date. The payment of such interest shall not foreclose M.I.T. from
exercising any other rights it may have as a consequence of the lateness of any
payment.


                         ARTICLE 6 - PATENT PROSECUTION

     6.1  M.I.T. shall apply for, seek prompt issuance of, and maintain during
the term of this Agreement the PATENT RIGHTS in the United States and in the
foreign countries listed in Appendix CEI-B hereto. Appendix CEI-B may be amended
by verbal agreement of both parties, such agreement to be confirmed in writing
within ten (10) days. The prosecution, filing and maintenance of all PATENT
RIGHTS patents and applications shall be the primary responsibility of M.I.T.;
provided, however, LICENSEE shall have reasonable opportunities to advise M.I.T.
and shall cooperate with M.I.T. in such prosecution, filing and maintenance of
all patents and applications included within the PATENT RIGHTS.

     6.2  Payment of all fees and costs relating to the filing, prosecution, and
maintenance of the PATENT RIGHTS shall be the responsibility of LICENSEE,
whether such fees and costs were incurred before or after the date of this
Agreement. LICENSEE shall have the right to approve the attorney selected by
M.I.T. LICENSEE may elect to discontinue all or a portion of the prosecution of
the PATENT RIGHTS, provided that LICENSEE gives M.I.T. reasonable notice, so
that M.I.T. may, at its own expense, elect to preserve those rights.


                            ARTICLE 7 - INFRINGEMENT
                            ------------------------
     7.1  Each party shall inform the other party prompfly in writing of any
alleged infringement of the PATENT RIGHTS by a third party and of any available
evidence thereof.

     7.2  During the term of exclusivity of this Agreement, LICENSEE shall have
the right, but shall not be obligated, to prosecute at its own expense all
infringements of the PATENT RIGHTS and, in furtherance of such right, M.I.T.
hereby agrees that LICENSEE may include M.I.T. as a party plaintiff in any such
suit, with6ut expense to M.I.T.. The total cost of any such infringement action
commenced or defended solely by LICENSEE shall be borne by LICENSEE and LICENSEE
shall keep any recovery or damages for past infringement derived therefrom.
<PAGE>
 
                                      -9-


     7.3  If within six (6) months after having been notified of any alleged
infringement, LICENSEE shall have been unsuccessful in persuading the alleged
infringer to desist and shall not have brought and shall not be diligently
prosecuting an infringement action, or if LICENSEE shall notify M.I.T. at any
time prior thereto of its intention not to bring suit against any alleged
infringer then, and in those events only, M.I.T. shall have the right, but shall
not be obligated, to prosecute at its own expense any infringement of the PATENT
RIGHTS and M.I.T. may, for such purposes, use the name of LICENSEE as party
plaintiff. No settlement, consent judgment or other voluntary final disposition
of the suit may be entered into without the consent of M.I.T. and LICENSEE,
which consent shall not unreasonably be withheld.

     7.4  In the event that LICENSEE shall undertake the enforcement and/or
defense of the PATENT RIGHTS by litigation, LICENSEE may withhold up to fifty
percent (50%) of the payments otherwise thereafter due M.I.T. under Article 4
hereunder and apply the same toward reimbursement of up to half of LICENSEE's
expenses, including reasonable attorneys' fees, in connection therewith. Any
recovery of damages by LICENSEE for each such suit shall be applied first in
satisfaction of any unreimbursed expenses and legal fees of LICENSEE relating to
such suit, and next toward reimbursement of M.I.T. for any payments under
Article 4 past due or withheld and applied pursuant to this Article 7. The
balance remaining from any such recovery shall be divided so that the fraction
of the recovery due M.I.T. is calculated by creating a fraction, the numerator
of which is the amount of royalties withheld, and the denominator of which is
the cost of litigation paid by LICENSEE, but in no event shall such sum be less
than Twelve Percent (12%) of the net recovery.

     7.5  In the event that a declaratory judgment action alleging invalidity or
noninfringement of any of the PATENT RIGHTS shall be brought against LICENSEE,
M.I.T., at its option, shall have the right, within thirty (30) days after
commencement of such action, to intervene and take over the sole defense of the
action at its own expense.

     7.6  In any infringement suit as either party may institute to enforce the
PATENT RIGHTS pursuant to this Agreement, the other party hereto shall, at the
request and expense of the party initiating such suit, cooperate in all respects
and, to the extent possible, have its employees testify when requested and make
available relevant records, papers, information, samples, specimens, and the
like.

     7.7  LICENSEE, during the exclusive penod of this Agreement, shall have the
sole right in accordance with the terms and conditions herein to sublicense any
alleged infringer for future use of the PATENT RIGHTS. Any upfront fees as part
of such a sublicense shall be distributed according to Article 7.4; other
royalties shall be treated per Article 4.

     3.5  If LICENSEE has diligently been pursuing the FDA approval required to
sell LICENSED PRODUCTS or products utilizing LICENSED PROCESSES on the
commercial market, and can demonstrate such diligence to M.I.T. by means of
written documents, then LICENSEE may request a reasonable revision to the sales

<PAGE>
 
                                      -6-

          (i)   One-third (1/3) of the non-reimbursed sum plus Six Thousand Two
                Hundred Fifty Dollars ($6,250) is due upon the execution of this
                Agreement;

          (ii)  One-third (1/3) of the non-reimbursed sum plus Three Thousand
                One Hundred Twenty-Five Dollars ($3,125) is due one (1) year
                after the EFFECTIVE DATE of this Agreement;

          (iii) One-third (1/3) of the non-reimbursed sum is due two (2) years
                after the EFFECTIVE DATE of this Agreement;

     (b)  For LICENSED PRODUCTS and LICENSED PROCESSES which do not contain a
          substantial technical contribution, improvement, or change developed
          by LICENSEE, Running Royalties in an amount equal to Two Percent (2%)
          of the NET SALES of the LICENSED PRODUCTS leased or sold by or for
          LICENSEE and/or its SUBLICENSEE(S).

     (c)  For LICENSED PRODUCTS and LICENSED PROCESSES containing a substantial
          technical contribution, improvement, or change developed by LICENSEE,
          Running Royalties in an amount equal to One and One-Half Percent
          (1.5%) of the NET SALES of the LICENSED PRODUCTS leased or sold by
          SUBLICENSEE(S), or Twelve Percent (12%) of gross revenue received by
          LICENSEE from SUBLICENSEE(S), whichever of the two above referenced
          means of calculating sublicensing revenue yields a smaller number.

     (d)  License Maintenance Fees of Five Thousand Dollars ($5,000) per year
          payable on January 1, 1995 and on January 1 of each subsequent year

          however, that the License Maintenance Fee and sublicense royalties
          subsequently due under subparagraph 4.1(d) for each said year, if any,
          shall be creditable against Running Royalties for said year. No
          License Maintenance Fees are due during the non-exclusive period of
          this License Agreement.


     4.2  All payments due hereunder shall be paid in full, without deduction of

paid by LICENSEE. if Royalties were paid on billings that were subsequently
uncollected, such overpaid Royalties will be deducted from those due in
subsequent periods.

     4.3  No multiple royalties shall be payable because any LICENSED PRODUCT,
its manufacture, use, lease or sale are or shall be covered by more than one
PATENT RIGHTS patent application or PATENT RIGHTS patent licensed under this
Agreement. If a single product is covered by more than LICENSE AGREEMENT, then
the total royalty paid to M.I.T. on such product shall not exceed the maximum
royalty applicable under any single LICENSE AGREEMENT.

     4.4  Royalty payments shall be paid in United States dollars in Cambridge,
Massachusetts, or at such other place as M.I.T. may reasonably designate
consistent with the laws and regulations controlling in any foreign country. If
any currency conversion shall be required in connection with the payment of 
royalties hereunder, such conversion shall be made by using the exchange rate
<PAGE>
 
                                      -7-

prevailing at the Chase Manhattan Bank (N.A.) on the last business day of the
calendar quarterly reporting period to which such royalty payments relate.


                        ARTICLE 5 - REPORTS AND RECORDS
                        -------------------------------

     5.1  LICENSEE shall keep full, true and accurate books of account
containing all particulars that may be necessary for the purpose of showing the
amounts payable to M.I.T. hereunder. Said books of account shall be kept at
LICENSEE's principal place of business or the principal place of business of the
appropriate division of LICENSEE to which this Agreement relates. Said books and
the supporting data shall be open at all reasonable times for three (3) years
following the end of the calendar year to which they pertain, to the inspection
of M.I.T. or its agents for the purpose of verifying LICENSEE's royalty
statement or compliance in other respects with this Agreement. Should such
inspection lead to the discovery of a greater than ten percent (10%) discrepancy
in reporting, LICENSEE agrees to pay half the cost of such inspection.

     5.2  LICENSEE, within sixty (60) days after December 31 of each year, shall
deliver to M.I.T. true and accurate reports, giving such particulars of the
business conducted by LICENSEE and its sublicensees during the preceding year
under this Agreement as shall be pertinent to a royalty accounting hereunder.
These shall include at least the following:

     (a)  number of LICENSED PRODUCTS manufactured and sold by LICENSEE and all
          sublicensees;

     (b)  total billings for LICENSED PRODUCTS sold by LICENSEE and all
          sublicensees;

LICENSEE's fiscal year, LICENSEE shall provide M.I.T. with LICENSEE's certified
financial statements for the preceding fiscal year including, at a minimum, a
Balance Sheet and an Operating Statement.

     5.5  The royalty payments set forth in this Agreement and amounts due under

on the due date. The payment of such interest
<PAGE>
 
                                      -8-

shall not foreclose M.I.T. from exercising any other rights it may have as a
consequence of the lateness of any payment.


                         ARTICLE 6 - PATENT PROSECUTION
                         ------------------------------

     6.1  M.I.T. shall apply for, seek prompt issuance of, and maintain during
the term of this Agreement the PATENT RIGHTS in the United States and in the
foreign countries listed in Appendix P-B hereto. Appendix P-B may be amended by
verbal agreement of both parties, such agreement to be confirmed in writing
within ten (10) days. The prosecution, filing and maintenance of all PATENT
RIGHTS patents and applications shall be the primary responsibility of M.I.T.;
provided, however, LICENSEE shall have reasonable opportunities to advise M.I.T.
and shall cooperate with M.I.T. in such prosecution, filing and maintenance of
all patents and applications included within the PATENT RIGHTS.

     6.2  Payment of all fees and costs relating to the filing, prosecution, and
maintenance of the PATENT RIGHTS shall be the responsibility of LICENSEE,
whether such fees and costs were incurred before or after the date of this
Agreement. LICENSEE shall have the right to approve the attorney selected by
M.I.T. LICENSEE may elect to discontinue all or a portion of the prosecution of
the PATENT RIGHTS, provided that LICENSEE gives M.I.T. reasonable notice, so
that M.I.T. may, at its own expense, elect to preserve those rights.


                            ARTICLE 7- INFRINGEMENT
                            -----------------------

     7.1  Each party shall inform the other party promptly in writing of any
alleged infringement of the PATENT RIGHTS by a third party and of any available
evidence thereof.

     7.2  During the term of exclusivity of this Agreement, LICENSEE shall have
the right, but shall not be obligated, to prosecute at its own expense all
infringements of the PATENT RIGHTS and, in furtherance of such right, M.I.T.
hereby agrees that LICENSEE may include M.I.T. as a party plaintiff in any such
suit, without expense to M.I.T.. The total cost of any such infringement action
commenced or defended solely by LICENSEE shall be borne by LICENSEE and LICENSEE
shall keep any recovery or damages for past infringement derived therefrom.

     7.3  If within six (6) months after having been notified of any alleged
infringement, LICENSEE shall have been unsuccessful in persuading the alleged
infringer to desist and shall not have brought and shall not be diligently
prosecuting an infringement action, or if LICENSEE shall notify M.I.T. at any
time prior thereto of its intention not to bring suit against any alleged
infringer then, and in those events only, M.I.T. shall have the right, but shall
not be obligated, to prosecute at its own expense any infringement of the PATENT
RIGHTS and M.I.T. may, for such purposes, use the name of LICENSEE as party
plaintiff. No settlement, consent judgment or other
<PAGE>
 
                                      -9-

voluntary final disposition of the suit may be entered into without the consent
of M.I.T. and LICENSEE, which consent shall not unreasonably be withheld.

     7.4  In the event that LICENSEE shall undertake the enforcement and/or
defense of the PATENT RIGHTS by litigation, LICENSEE may withhold up to fifty
percent (50%) of the payments otherwise thereafter due M.I.T. under Article 4
hereunder and apply the same toward reimbursement of up to half of LICENSEE's
expenses, including reasonable attorneys' fees, in connection therewith. Any
recovery of damages by LICENSEE for each such suit shall be applied first in
satisfaction of any unreimbursed expenses and legal fees of LICENSEE relating to
such suit, and next toward reimbursement of M.I.T. for any payments under
Article 4 past due or withheld and applied pursuant to this Article 7. The
balance remaining from any such recovery shall be divided so that the fraction
of the recovery due M.I.T. is calculated by creating a fraction, the numerator
of which is the amount of royalties withheld, and the denominator of which is
the cost of litigation paid by LICENSEE, but in no event shall such sum be less
than Twelve Percent (12%) of the net recovery.

     7.5  In the event that a declaratory judgment action alleging invalidity or
noninfringement of any of the PATENT RIGHTS shall be brought against LICENSEE,
M.I.T., at its option, shall have the right, within thirty (30) days after
commencement of such action, to intervene and take over the sole defense of the
action at its own expense.

     7.6  In any infringement suit as either party may institute to enforce the
PATENT RIGHTS pursuant to this Agreement, the other party hereto shall, at the
request and expense of the party initiating such suit, cooperate in all respects
and, to the extent possible, have its employees testify when requested and make
available relevant records, papers, information, samples, specimens, and the
like.

     7.7  LICENSEE, during the exclusive period of this Agreement, shall have
the sole right in accordance with the terms and conditions herein to sublicense
any alleged infringer for future use of the PATENT RIGHTS. Any upfront fees as
part of such a sublicense shall be distributed according to Article 7.4; other
royalties shall be treated per Article 4.


                         ARTICLE 8 - PRODUCT LIABILITY
                         -----------------------------

any person or persons or out of any damage to property and against any other

LICENSEE hereunder.

M.I.T. in regard to events covered by Paragraph 8.1 above. Such insurance shall
be written by a reputable insurance company authorized to do business in the
Commonwealth of Massachusetts, shall list M.I.T. as an additional named insured
thereunder and shall require thirty (30) days written notice to be given to
M.I.T. prior to any cancellation or material change thereof. The limits of such
occurrence shall not be less than One Million Dollars ($1,000,000) per
occurrence with an aggregate of Three Million Dollars ($3,000,000) for personal
injury or death, and One Million Dollars ($1,000,000) per occurrence with an
aggregate of Three Million Dollars ($3,000,000) for property damage. LICENSEE
shall provide M.I.T. with Certificates of Insurance evidencing the same.

     8.3  EXCEPT AS OTHERWISE EXPRESSLY SET FORTH IN THIS AGREEMENT, M.I.T.
MAKES NO REPRESENTATIONS AND EXTENDS NO WARRANTIES OF ANY KIND, EITHER EXPRESS
OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS
FOR A PARTICULAR PURPOSE, AND VALIDITY OF PATENT RIGHTS CLAIMS, ISSUED OR
PENDING. NOTHING IN THIS AGREEMENT SHALL BE CONSTRUED AS A REPRESENTATION MADE
OR WARRANTY GIVEN BY M.I.T. THAT THE PRACTICE BY LICENSEE OF THE LICENSE GRANTED
HEREUNDER SHALL NOT INFRINGE THE PATENT RIGHTS OF ANY THIRD PARTY.

     8.4  M.I.T. hereby represents and warrants, to the best of its knowledge
and belief, to LICENSEE that the execution, delivery and performance of this
Agreement by M.I.T. does not, and will not, violate any commitments or
undertakings to which M.I.T. may be bound.


                          ARTICLE 9 - EXPORT CONTROLS
                          ---------------------------

regulations controlling the export of technical data, computer software,
laboratory prototypes and other commodities (including the Arms Export Control
Act, as amended and the Export Administration Act of 1979), and that its
obligations hereunder are contingent on compliance with applicable United States
export laws and regulations. The transfer of certain technical data and
commodities may require a license from the cognizant agency of the United States
Government and/or written assurances by LICENSEE that LICENSEE shall not export
data or commodities to certain foreign countries without prior approval of such
agency. M.I.T. neither represents that a license shall not be required nor that,
if required, it shall be issued.

patents and/or applications comprising the PATENT RIGHTS. Such statements may
appear in the Private Placement Memoranda to be circulated by CardioDynamics,
Inc., or in filings in compliance with securities laws. LICENSEE shall not use
the names or trademarks of the Massachusetts Institute of Technology, nor any
adaptation thereof, nor the names of any of its employees to imply that M.I.T.
endorses the LICENSED PRODUCTS sold by LICENSEE.

                        ARTICLE 12 - DISPUTE RESOLUTION
                        -------------------------------

     12.1  For any and all claims, disputes or controversies arising out of, or
in connection with this Agreement, including any dispute relating to patent
validity or infringement, which the parties shall be unable to resolve within
sixty (60) days, the party raising such dispute shall promptly advise the other

authority to bind such party, and shall additionally have advised the other
party in writing of the name and title of such representative. By not later than
ten (10) business days after the date of such notice of dispute, such
representatives shall schedule a date for a mediation hearing with the Cambridge
Dispute Settlement Center or Endispute Inc. in Cambridge, Massachusetts. If the
representatives of the parties have not been able to resolve the dispute within

invention in the nature of an improvement is developed by Richard Cohen in the
context of his consulting activity with LICENSEE or in the context of his
activities as a University Professor at M.I.T., M.I.T. will approach LICENSEE in
good faith to negotiate a reasonable resolution.

     12.3  Notwithstanding the foregoing, nothing in this Article shall be
construed to waive any rights or timely performance of any obligations existing
under this Agreement.

<PAGE>
 
                                      -4-

     (b)  the expiration of fifteen (15) years after the EFFECTIVE DATE of this

          approval has been submitted to the FDA for a LICENSED PRODUCT prior to
          the expiration of that fifteen (15) year period, then the time spent
          by that application in the FDA shall be added to the fifteen (15) year
          period.


     2.4  At the end of the exclusive period, the license granted hereunder
shall become nonexclusive and shall extend to the end of the term or terms for

rights upon LICENSEE by implication, estoppel or otherwise as to any technology
not specifically set forth in Appendices CSI-A, CSI-B, and CSI-C hereof.

          and kind of personnel and time budgeted and planned for each phase of
          development of the LICENSED PRODUCTS and LICENSED PROCESSES in the

</TABLE> 

     3.4  LICENSEE's failure to perform in accordance with Paragraphs 3.1, 3.2
and 3.3 above shall be grounds for M.I.T. to terminate this Agreement pursuant
to Paragraph 13.3 hereof.

     3.5  If LICENSEE has diligently been pursuing the FDA approval required to
sell LICENSED PRODUCTS or products utilizing LICENSED PROCESSES on the
commercial market, and can demonstrate such diligence to M.I.T. by means of
written documents, then LICENSEE may request a reasonable revision to the sales
milestones in section 3.3, which revision shall not unreasonably be withheld.


                             ARTICLE 4 - ROYALTIES

     (a)  License Issue Fee equal to the non-reimbursed sum spent by M.I.T.
          prior to the OPTION PERIOD to file, prosecute, and maintain the PATENT
          RIGHTS listed in Appendices CSI-A and CSI-B plus Nine Thousand Three
          Hundred Seventy-Five Dollars ($9,375), such Issue Fee payable

          (i)   One-third (1/3) of the non-reimbursed sum plus Six Thousand Two
                Hundred Fifty Dollars ($6,250) is due upon the execution of this
                Agreement;

          (ii)  One-third (1/3) of the non-reimbursed sum plus Three Thousand
                One Hundred Twenty-Five Dollars ($3,125) is due one (1) year
                after the EFFECTIVE DATE of this Agreement;

          (iii) One-third (1/3) of the non-reimbursed sum is due two (2) years
                after the EFFECTIVE DATE of this Agreement;

     (b)  For LICENSED PRODUCTS and LICENSED PROCESSES which do not contain a
          substantial technical contribution, improvement, or change developed
          by LICENSEE, Running Royalties in an amount equal to Two Percent (2%)
          of the NET SALES of the LICENSED PRODUCTS leased or sold by/or for
          LICENSEE and/or its SUBLICENSEE(S).


     (c)  For LICENSED PRODUCTS and LICENSED PROCESSES containing a substantial
          technical contribution, improvement, or change developed by LICENSEE,
          Running Royalties in an amount equal to One and One-Half Percent
          (1.5%) of the NET SALES of the LICENSED PRODUCTS leased or sold by
          SUBLICENSEE(S), or Twelve Percent (12%) of gross revenue received by
          LICENSEE from SUBLICENSEE(S), whichever of the two above referenced
          means of calculating sublicensing revenue yields a smaller number.

          payable on January 1, 1995, January 1, 1996, January 1, 1997, January

          Maintenance Fee and sublicense royalties subsequently due under
          subparagraph 4.1(d) for each said year, if any, shall be creditable
          against Running Royalties for said year.

     (e)  License Maintenance Fees of Ten Thousand Dollars ($10,000) per year
          payable on January 1, 2000 and on January 1 of each subsequent year
          thereafter during the exclusive period of this Agreement; provided,
          however, that the License Maintenance Fee and sublicense royalties
          subsequently due under subparagraph 4.1(d) for each said year, if any,
          shall be creditable against Running Royalties for said year. No
          License Maintenance Fees are due during the non-exclusive period of
          this License Agreement.


     4.2  All payments due hereunder shall be paid in full, without deduction of
taxes or other fees which may be imposed by any government and which shall be
paid by LICENSEE. If Royalties were paid on billings that were subsequently
uncollected, such overpaid Royalties will be deducted from those due in 
subsequent periods.

                                      -7-

     4.3  No multiple royalties shall be payable because any LICENSED PRODUCT,
its manufacture, use, lease or sale are or shall be covered by more than one
PATENT RIGHTS patent application or PATENT RIGHTS patent licensed under this
Agreement. If a single product is covered by more than one LICENSE AGREEMENT,
then the total royalty paid to M.I.T. on such product shall not exceed the
maximum royalty applicable to any single LICENSE AGREEMENT.

     4.4  Royalty payments shall be paid in United States dollars in Cambridge,
Massachusetts, or at such other place as M.I.T. may reasonably designate
consistent with the laws and regulations controlling in any foreign country. If
any currency conversion shall be required in connection with the payment of
royalties hereunder, such conversion shall be made by using the exchange rate
prevailing at the Chase Manhattan Bank (N.A.) on the last business day of the
calendar quarterly reporting period to which such royalty payments relate.


                        ARTICLE 5 - REPORTS AND RECORDS
                        -------------------------------

     5.1  LICENSEE shall keep full, true and accurate books of account
containing all particulars that may be necessary for the purpose of showing the
amounts payable to M.I.T. hereunder. Said books of account shall be kept at
LICENSEE's principal place of business or the principal place of business of the
appropriate division of LICENSEE to which this Agreement relates. Said books and

following the end of the calendar year to which they pertain, to the inspection
of M.I.T. or its agents for the purpose of verifying LICENSEE's royalty
statement or compliance in other respects with this Agreement. Should such
inspection lead to the discovery of a greater than ten percent (10%) discrepancy
in reporting, LICENSEE agrees to pay half the cost of such inspection.

     5.2  LICENSEE, within sixty (60) days after December 31, of each year,
shall deliver to M.I.T. true and accurate reports, giving such particulars of

     5.3  With each such report submitted, LICENSEE shall pay to M.I.T. the
royalties due and payable under this Agreement. If no royalties shall be due,
LICENSEE shall so report.

     5.4  On or before the ninetieth (90th) day following the close of
LICENSEE's fiscal year, LICENSEE shall provide M.I.T. with LICENSEE's certified
financial statements for the preceding fiscal year including, at a minimum, a
Balance Sheet and an Operating Statement.

     5.5  The royalty payments set forth in this Agreement and amounts due under
Article 6 shall, if overdue, bear interest until payment at a per annum rate two
percent (2%) above the prime rate in effect at the Chase Manhattan Bank (N. A.)
on the due date. The payment of such interest shall not foreclose M.I.T. from
exercising any other rights it may have as a consequence of the lateness of any
payment.


                         ARTICLE 6 - PATENT PROSECUTION
                         ------------------------------

     6.1  M.I.T. shall apply for, seek prompt issuance of, and maintain during
the term of this Agreement the PATENT RIGHTS in the United States and in the
foreign countries listed in Appendix CSI-B hereto. Appendix CS I-B may be
amended by verbal agreement of both parties, such agreement to be confirmed in
writing within ten (10) days. The prosecution, filing and maintenance of all
PATENT RIGHTS patents and applications shall be the primary responsibility of
M.I.T.; provided, however, LICENSEE shall have reasonable opportunities to
advise M.I.T. and shall cooperate with M.I.T. in such prosecution, filing and
maintenance of all patents and applications included within the PATENT RIGHTS.

     6.2  Payment of all fees and costs relating to the filing, prosecution, and
maintenance of the PATENT RIGHTS shall be the responsibility of LICENSEE,
whether such fees and costs were incurred before or after the date of this
Agreement. LICENSEE shall have the right to approve the attorney selected by
M.I.T. LICENSEE may elect to discontinue all or a portion of the prosecution of
the PATENT RIGHTS, provided that LICENSEE gives M.I.T. reasonable notice, so
that M.I.T. may, at its own expense, elect to preserve those rights.


                            ARTICLE 7 - INFRINGEMENT
                            ------------------------

     7.1  Each party shall inform the other party promptly in writing of any
alleged infringement of the PATENT RIGHTS by a third party and of any available
evidence thereof.

     7.2  During the term of exclusivity of this Agreement, LICENSEE shall have
the right, but shall not be obligated, to prosecute at its own expense all
infringements of the PATENT RIGHTS and, in furtherance of such right, M.I.T.
hereby agrees that LICENSEE may include M.I.T. as a party plaintiff in any such
suit, without expense to M.I.T.. The total cost of any such infringement action
commenced or defended solely by LICENSEE shall be borne by LICENSEE and LICENSEE
shall keep any recovery or damages for past infringement derived therefrom.
<PAGE>
 
                                      -9-

     7.3  If within six (6) months after having been notified of any alleged
infringement, LICENSEE shall have been unsuccessful in persuading the alleged
infringer to desist and shall not have brought and shall not be diligently
prosecuting an infringement action, or if LICENSEE shall notify M.I.T. at any
time prior thereto of its intention not to bring suit against any alleged
infringer then, and in those events only, M.I.T. shall have the right, but shall
not be obligated, to prosecute at its own expense any infringement of the PATENT
RIGHTS and M.I.T. may, for such purposes, use the name of LICENSEE as party
plaintiff. No settlement, consent judgment or other voluntary final disposition
of the suit may be entered into without the consent of M.I.T. and LICENSEE,
which consent shall not unreasonably be withheld.

     7.4  In the event that LICENSEE shall undertake the enforcement and/or
defense of the PATENT RIGHTS by litigation, LICENSEE may withhold up to fifty
percent (50%) of the payments otherwise thereafter due M.I.T. under Article 4
hereunder and apply the same toward reimbursement of up to half of LICENSEE's
expenses, including reasonable attorneys' fees, in connection therewith. Any
recovery of damages by LICENSEE for each such suit shall be applied first in
satisfaction of any unreimbursed expenses and legal fees of LICENSEE relating to
such suit, and next toward reimbursement of M.I.T. for any payments under
Article 4 past due or withheld and applied pursuant to this Article 7. The
balance remaining from any such recovery shall be divided so that the fraction
of the recovery due M.I.T. is calculated by creating a fraction, the numerator
of which is the amount of royalties withheld, and the denominator of which is
the cost of litigation paid by LICENSEE, but in no event shall such sum be less
than Twelve Percent (12%) of the net recovery.

     7.5  In the event that a declaratory judgment action alleging invalidity or
noninfringement of any of the PATENT RIGHTS shall be brought against LICENSEE,
M.I.T., at its option, shall have the right, within thirty (30) days after
commencement of such action, to intervene and take over the sole defense of the
action at its own expense.

     7.6  In any infringement suit as either party may institute to enforce the
PATENT RIGHTS pursuant to this Agreement, the other party hereto shall, at the
request and expense of the party initiating such suit, cooperate in all respects
and, to the extent possible, have its employees testify when requested and make
available relevant records, papers, information, samples, specimens, and the
like.

     7.7  LICENSEE, during the exclusive period of this Agreement, shall have
the sole right in accordance with the terms and conditions herein to sublicense
any alleged infringer for future use of the PATENT RIGHTS. Any upfront fees as
part of such a sublicense shall be distributed according to Article 7.4; other
royalties shall be treated per Article 4.

                         ARTICLE 8 - PRODUCT LIABILITY
                         -----------------------------

     8.1  LICENSEE shall at all times during the term of this Agreement and
thereafter, indemnify, defend and hold M.I.T., its trustees, officers, employees
and affiliates, harmless against all claims and expenses, including legal
expenses and reasonable attorneys' fees, arising out of the death of or injury
to any person or persons or out of any damage to property and against any other
claim, proceeding, demand, expense and liability of any kind whatsoever
resulting from the production, manufacture, sale, use, lease, consumption or
advertisement of the LICENSED PRODUCT(s) and/or LICENSED PROCESS(es) or arising
from any obligation of LICENSEE hereunder.

     8.2  Before delivery of a LICENSED PRODUCT, LICENSEE shall obtain and carry
in full force and effect liability insurance which shall protect LICENSEE and
M.I.T. in regard to events covered by Paragraph 8.1 above. Such insurance shall
be written by a reputable insurance company authorized to do business in the
Commonwealth of Massachusetts, shall list M.I.T. as an additional named insured
thereunder and shall require thirty (30) days written notice to be given to
M.I.T. prior to any cancellation or material change thereof. The limits of such
occurrence shall not be less than One Million Dollars ($1,000,000) per
occurrence with an aggregate of Three Million Dollars ($3,000,000) for personal
injury or death, and One Million Dollars ($1,000,000) per occurrence with an
aggregate of Three Million Dollars ($3,000,000) for property damage. LICENSEE
shall provide M.I.T. with Certificates of Insurance evidencing the same.

     8.3  EXCEPT AS OTHERWISE EXPRESSLY SET FORTH IN THIS AGREEMENT, M.I.T.
MAKES NO REPRESENTATIONS AND EXTENDS NO WARRANTIES OF ANY KIND, EITHER EXPRESS
OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS
FOR A PARTICULAR PURPOSE, AND VALIDITY OF PATENT RIGHTS CLAIMS, ISSUED OR
PENDING. NOTHING IN THIS AGREEMENT SHALL BE CONSTRUED AS A REPRESENTATION MADE
OR WARRANTY GIVEN BY M.I.T. THAT THE PRACTICE BY LICENSEE OF THE LICENSE GRANTED
HEREUNDER SHALL NOT INFRINGE THE PATENT RIGHTS OF ANY THIRD PARTY.

     8.4  M.I.T. hereby represents and warrants, to the best of its knowledge
and belief, to LICENSEE that the execution, delivery and performance of this
Agreement by M.I.T. does not, and will not, violate any commitments or
undertakings to which M.I.T. may be bound.



                          ARTICLE 9 - EXPORT CONTROLS
                          ---------------------------

     It is understood that M.I.T. is subject to United States laws and
regulations controlling the export of technical data, computer software,
laboratory prototypes and other commodities
<PAGE>
 
                                     -11-

(including the Arms Export Control Act, as amended and the Export Administration
Act of 1979), and that its obligations hereunder are contingent on compliance
with applicable United States export laws and regulations. The transfer of
certain technical data and commodities may require a license from the cognizant
agency of the United States Government and/or written assurances by LICENSEE
that LICENSEE shall not export data or commodities to certain foreign countries
without prior approval of such agency. M.I.T. neither represents that a license
shall not be required nor that, if required, it shall be issued.


                         ARTICLE 10 - NON-USE OF NAMES
                         -----------------------------

     LICENSEE shall not use the names or trademarks of the Massachusetts
Institute of Technology, nor any adaptation thereof, nor the names of any of its
employees, in any advertising, promotional or sales literature without prior
written consent obtained from M.I.T., or said employee, in each case, except
that LICENSEE may state that it is licensed by M.I.T. under one or more of the
patents and/or applications comprising the PATENT RIGHTS. Such statements may
appear in the Private Placement Memoranda to be circulated by KBL Healthcare,
Inc., or in filings in compliance with securities laws. LICENSEE shall not use
the names or trademarks of the Massachusetts Institute of Technology, nor any
adaptation thereof, nor the names of any of its employees to imply that M.I.T.
endorses the LICENSED PRODUCTS sold by LICENSEE.


                            ARTICLE 11 - ASSIGNMENT
                            -----------------------

     11.1  M.I.T. and LICENSEE agree that one of the main purposes of this
Agreement is for LICENSEE to add substantial technical value to the PATENT
RIGHTS.

     11.2  LICENSEE may assign this agreement with M.I.T.'s written consent,
which consent shall not unreasonably be withheld, provided that LICENSEE has
fulfilled all the diligence milestones in Article 3, up to and including section
3.2 development of a working commercial prototype in the PRODUCT AREA.
Otherwise, LICENSEE shall have no right to assign, and any attempt to assign
shall be null and void.


                        ARTICLE 12 - DISPUTE RESOLUTION
                        -------------------------------

     12.1  For any and all claims, disputes or controversies arising out of, or
in connection with this Agreement, including any dispute relating to patent
validity or infringement, which the parties shall be unable to resolve within
sixty (60) days, the party raising such dispute shall promptly advise the other
party of such claim, dispute or controversy in a writing which describes in
reasonable detail the nature of such dispute. By not later than five (5)
business days after the recipient has received such notice of dispute, each
party shall have selected for itself a representative who shall have the
authority to bind such party, and shall additionally have advised
<PAGE>
 
                                     -12-

the other party in writing of the name and title of such representative. By not
later than ten (10) business days after the date of such notice of dispute, such
representatives shall schedule a date for a mediation hearing with the Cambridge
Dispute Settlement Center or Endispute Inc. in Cambridge, Massachusetts. If the
representatives of the parties have not been able to resolve the dispute within
fifteen (15) business days after such mediation hearing, the parties shall have
the right to pursue any other remedies legally available to resolve such dispute
in either the Courts of the Commonwealth of Massachusetts or in the United
States District Court for the District of Massachusetts, to whose jurisdiction
for such purposes M.I.T. and LICENSEE each hereby irrevocably consents and
submits.

     12.2  M.I.T. is aware that Richard Cohen is a consultant to LICENSEE and is
conducting research in the field of the patent rights and that Richard Cohen is
obligated to assist LICENSEE in protecting inventions developed by him at
LICENSEE's laboratory. In the event that it is unclear whether a particular
invention in the nature of an improvement is developed by Richard Cohen in the
context of his consulting activity with LICENSEE or in the context of his
activities as a University Professor at M.I.T., M.I.T. will approach LICENSEE in
good faith to negotiate a reasonable resolution.

     12.3  Notwithstanding the foregoing, nothing in this Article shall be
construed to waive any rights or timely performance of any obligations existing
under this Agreement.


                            ARTICLE 13 - TERMINATION
                            ------------------------

     13.1  If LICENSEE shall cease to carry on its business, this Agreement
shall terminate upon notice by M.I.T.

     13.2  Should LICENSEE fail to make any payment whatsoever due and payable
to M.I.T. hereunder, M.I.T. shall have the right to terminate this Agreement
effective on thirty (30) days' notice, unless LICENSEE shall make all such
payments to M.I.T. within said thirty (30) day period. Upon the expiration of
the thirty (30) day period, if LICENSEE shall not have made all such payments to
M.I.T., the rights, privileges and license granted hereunder shall automatically
terminate.

     13.3  Upon any material breach or default of this Agreement by LICENSEE,
other than those occurrences set out in Paragraphs 13.1 and 13.2 hereinabove,
which shall always take precedence in that order over any material breach or
default referred to in this Paragraph 13.3, M.I.T. shall have the right to
terminate this Agreement and the rights, privileges and license granted
hereunder effective on ninety (90) days' notice to LICENSEE. Such termination
shall become automatically effective unless LICENSEE shall have cured any such
material breach or default prior to the expiration of the ninety (90) day
period.
<PAGE>
 
                                     -13-

     13.4  LICENSEE shall have the right to terminate this Agreement at any time
on six (6) months' notice to M.I.T., and upon payment of all amounts due M.I.T.
through the effective date of the termination.

     13.5  Upon termination of this Agreement for any reason, nothing herein
shall be construed to release either party from any obligation that matured
prior to the effective date of such termination. LICENSEE and any sublicensee
thereof may, however, after the effective date of such termination, sell all
LICENSED PRODUCTS, and complete LICENSED PRODUCTS in the process of manufacture
at the time of such termination and sell the same, provided that LICENSEE shall
pay to M.I.T. the Running Royalties thereon as required by Article 4 of this
Agreement and shall submit the reports required by Article 5 hereof on the sales
of LICENSED PRODUCTS.

     13.6  Upon termination of this Agreement for any reason, any sublicensee
not then in default shall have the right to seek a license from M.I.T. M.I.T.
agrees to negotiate such licenses in good faith under reasonable terms and
conditions.

                         ARTICLE 14 - PAYMENTS, NOTICES
                         ------------------------------
                            AND OTHER COMMUNICATIONS
                            ------------------------

                  ARTICLE 15 - MOST FAVORED LICENSEE
                  ----------------------------------

     If, during the non-exclusive period of this Agreement, M.I.T. grants a
license to another party under more favorable terms as a whole than those in
this Agreement, LICENSEE may, at no extra cost, elect a license under the more
favorable terms as a whole. M.I.T. shall notify and provide a copy to LICENSEE

                     -------------------------------------

     16.1  This Agreement shall be construed, governed, interpreted and applied
in accordance with the laws of the Commonwealth of Massachusetts, U.S.A., except
that questions affecting the construction and effect of any patent shall be
determined by the law of the country in which the patent was granted.

     16.2  The parties hereto acknowledge that this Agreement sets forth the
entire Agreement and understanding of the parties hereto as to the subject
matter hereof, and shall not be subject to any change or modification except by
the execution of a written instrument subscribed to by the parties hereto.

     16.3  The provisions of this Agreement are severable, and in the event that
any provisions of this Agreement shall be determined to be invalid or
unenforceable under any controlling body of the law, such invalidity or
unenforceability shall not in any way affect the validity or enforceability of
the remaining provisions hereof.

     16.4  LICENSEE agrees to mark the LICENSED PRODUCTS sold in the United
States with all applicable United States patent numbers. All LICENSED PRODUCTS
shipped to or sold in other countries shall be marked in such a manner as to
conform with the patent laws and practice of the country of manufacture or sale.

     16.5  The failure of either party to assert a right hereunder or to insist
upon compliance with any term or condition of this Agreement shall not
constitute a waiver of that right or excuse a similar subsequent failure to
perform any such term or condition by the other party.
